2 Low-speed range speed control P gain

Low-speed range speed control P gain operation selection Speed control P gain = "60% (initial value)" is equivalent to 120 rad/s (speed response of a single motor). Setting this

parameter higher speeds up the response, but setting this too high causes vibration and acoustic noise. Set the P gain value for speed control in the low-speed range in Pr.1400 and Pr.1401.

P gain response level The response to the setting value in P gain parameters (Pr.820, Pr.830, Pr.1400, and Pr.1401) differs depending on the

capacity and control method of the inverter.

The P gain for speed control in the low-speed range can be adjusted. When an inverter is connected to a lift, the inverter has a load immediately after the lift brake is released. For lift

applications, slow response may cause a delay in the brake opening. Adjusting the P gain in the low-speed range improves the response at low speeds, and shortens the time from startup to brake opening. This will contribute to a reduction in tact time.

CRANE FUNCTION MANUAL

Low-speed range speed control P gain operation The P gain operation during speed control in the low-speed range is determined by the Pr.1402 and Pr.1403 settings. When the actual speed reaches or exceeds the speed set in Pr.1403, Pr.820 Speed control P gain 1 (Pr.830 Speed

control P gain 2) is enabled. When the actual speed does not exceed the speed set in Pr.1402, the larger value of either Pr.1400 (Pr.1401) setting or

Pr.820 (Pr.830) setting is enabled. When the actual speed is equal to the speed between the Pr.1402 and Pr.1403 settings, the larger value of either the one

calculated from Pr.1400 (Pr.1401) setting and Pr.820 (Pr.830) setting, or Pr.820 (Pr.830) setting is enabled, as below.

NOTE When the Pr.1400 (Pr.1401) setting is smaller than the Pr.820 (Pr.830) setting, the speed control P gain is as below.

When the value same as Pr.1403 setting and above is set in Pr.1402, the speed control P gain is as below.

The low-speed range speed control P gain is valid under Real sensorless vector control, vector control, and PM sensorless vector control (when low-speed range high-torque characteristic is enabled).

For the details of Pr.820 (Pr.830), refer to the Instruction Manual (Detailed) of the FR-A800 inverter.

3 Shortest-time torque startup

When Pr.1404 = "1" and the inverter is not in stop status, the torque is generated by the shortest-time torque startup function.

NOTE The shortest-time torque startup function is available under Real sensorless vector control and vector control.

The torque is started up in the shortest time. When an inverter is connected to a lift, the load is applied immediately after the lift brake is released. For lift

applications, slow torque startup may cause a delay in the brake opening. Using the shortest-time torque startup function shortens the time from startup to brake opening. This will contribute to a reduction in tact time.

4 Inching time adjustment function

After the inverter output is stopped by turning OFF the start command, the inverter output cannot be restarted for the time set in Pr.1406.

When the start self-holding function is enabled and the start signal is turned ON within the time set in Pr.1406, the ON status is held.

When the output is shut off by the MRS signal, or when the inverter stops by a "0 Hz" frequency command while the start command is ON, the inverter output restarts even within the time set in Pr.1406.

NOTE When the output is stopped by simultaneously turning ON both the forward rotation command (STF) and the reverse rotation

command (STR), the inverter restarts after the time set in Pr.1406 has elapsed. At the first start after setting Pr.1406 "0", the inverter starts running without waiting for the inching prevention time. The inching time adjustment function is also enabled during the external JOG operation. When the inverter output is shut off during offline auto tuning, the inching time adjustment function is disabled. When the pre-excitation/servo ON signal (LX) is turned ON, or during the DC injection brake operation by turning ON the

external DC injection brake start signal (X13), the inching time adjustment function is disabled.

By setting a waiting time after the inverter is stopped until the inverter is restarted, inching in the setting time can be prevented.

When the inverter is repeatedly started and stopped for a short time, the overcurrent may occur due to the effect of the motor residual magnetic flux. Adjust the waiting time after the inverter is stopped until the inverter is restarted to suppress current.

running immediately. Do not get close to the motor or machine during the time set in Pr.1406 after the start command is ON, regardless of the motor or machine operating status.

5 Magnetic flux command during pre- excitation

When the pre-excitation signal (LX) is turned ON while the start command (STF/STR) is OFF, the inverter operates in the magnetic flux command value set in Pr.1407.

When the start command is ON after the LX signal is turned ON, the magnetic flux command value set in Pr.1407 is invalid, and the inverter operates in normal magnetic flux command value.

During deceleration after the start command is OFF or during DC injection brake operation, the inverter operates in normal magnetic flux command value.

NOTE The magnetic flux command value during pre-excitation is available under Real sensorless vector control and vector control. Under Real sensorless vector control, the minimum magnetic flux command value is 25%. (When the magnetic flux

command value is set less than 25%, the inverter operates at 25%.)

Adjusting the magnetic flux command during pre-excitation reduces the excitation ratio and power consumption during standby.

6 Load torque high-speed frequency control (mode 2)

For the load torque high speed frequency control (mode 1) and the stop-on-contact control, refer to the Instruction Manual (Detailed) of the FR- A800 inverter.

When "load torque high-speed frequency control (mode 2)" is not selected, the droop gain is internally restricted to 100% even if a value exceeding 100% is set.

Load torque high-speed frequency control is a function that automatically sets the operable frequency according to the load.

After starting the inverter, the inverter runs at high frequency with a light load, or at low frequency with a heavy load, depending of the value of the current. When light loads are moved up or down by a crane, the speed will accelerate automatically, which contributes to reduction in tact time.

CRANE FUNCTION MANUAL

Load torque high speed frequency control (mode 2) setting Set "4, 5 or 15" in Pr.270 Stop-on contact/load torque high-speed frequency control selection. When operating with the load torque high speed frequency function selection signal (X19) ON, the load torque high speed

frequency control (mode 2) is enabled.

Operation of load torque high-speed frequency control (mode 2) The maximum frequency (Pr.4 or Pr.5) is used as the target frequency for acceleration. When the output current (Iq) reaches or exceeds the torque current limit value (Iq limit level), acceleration is interrupted. When the output current (Iq) decreases by the interruption, acceleration starts again. By switching between acceleration and stopping, acceleration is controlled so that the torque current matches the torque

current limit value.

NOTE When the output frequency is between 0 and the Pr.273 setting, load torque high speed frequency control (mode 2) is not

activated. When the load torque high-speed frequency control (mode 2) is used under V/F control, performing offline auto tuning is

recommended in order to increase the accuracy. After setting Pr.80 Motor capacity and Pr.81 Number of motor poles according to a motor specification (selecting Advanced magnetic flux vector control), perform offline auto tuning by setting Pr.96 Auto tuning setting/status = "1 or 101". When the tuning completes, set "9999" in both Pr.80 and Pr.81 (select V/F control). For how to perform the offline auto tuning, refer to the Instruction Manual (Detailed) of the FR-A800.

The automatic restart after instantaneous power failure function, fast-response current limit operation, shortest acceleration/ deceleration, and optimum acceleration/deceleration are invalid.

Under the following operating conditions, the load torque high-speed frequency control (mode 2) is not available: PU operation (Pr.79), PU + External operation (Pr.79), JOG operation, PID control function operation (Pr.128), remote setting function operation (Pr.59), orientation control function operation, multi-speed setting (RH, RM, and RL signals), torque control, position control.

7 Overload detection

Constant speed signal (Y223 signal) When the range of the command frequency fluctuations is about 2 Hz/s or less while the inverter is running, the constant

speed signal (Y223) is turned ON. When the inverter stops, or when the range of the command frequency fluctuations is more than 2 Hz/s, the constant speed signal (Y223) is turned OFF.

For the Y223 signal, set "223 (positive logic) or 323 (negative logic)" in one of Pr.190 to Pr.196 (output terminal function selection) to assign the function to the output terminal.

NOTE The Y223 signal judges the constant speed status by the range of the command frequency fluctuations. The Y223 signal is

not turned ON immediately after the frequency has reached the target frequency. Changing the terminal assignment using Pr.190 to Pr.196 (output terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal.

Overload detection (Pr.864, Pr.1405, TU2 signal) During constant speed operation (the Y223 signal ON), when the motor torque is equal to or higher than the value set in

Pr.864 Torque detection for a continuous time equal to or longer than the value set in Pr.1405 Overload detection time, the overload detection signal (TU2) is turned ON. When the TU2 signal is ON, the TU2 signal stays ON until the inverter output stops.

For the TU2 signal, set "221 (positive logic) or 321 (negative logic)" in one of Pr.190 to Pr.196 (output terminal function selection) to assign the function to the output terminal.

The constant speed signal (Y223) can be output when the range of speed fluctuations is small. By the output of the constant speed signal, the load torque without the acceleration/deceleration torque can be confirmed. When this function is used together with the PLC function, the superordinate controller, etc., the control according to the load is enabled.

The overload can be detected during constant speed operation. When too much load is applied (overload) to a crane, the overload detection signal (TU2) output transmits the information to the superordinate controller.

8 Anti-sway control

Anti-sway control disabled signal (X54 signal) When anti-sway control is enabled, the travel distance between the positions where the crane starts deceleration and

where the crane stops becomes longer. For an emergency stop by a system using a position confirmation sensor, disable anti-sway control to shorten the stopping distance.

When anti-sway control is enabled (Pr.1073 Anti-sway control operation selection = "1") , turning ON the Anti-sway control disabled signal (X54) disables anti-sway control.

For the X54 signal, set "54" in any of Pr.178 to Pr.189 (input terminal function selection) to assign the function to the input terminal.

NOTE For the details of anti-sway control, refer to the Instruction Manual (Detailed) of the FR-A800 inverter. Changing the terminal assignment using Pr.178 to Pr.189 (input terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal.

NOTE While the inverter is stopped, or during DC injection brake operation (including zero speed control and servo lock), the Y222

signal is OFF. The Y222 signal is available under vector control or encoder feedback control. Changing the terminal assignment using Pr.190 to Pr.196 (output terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal.

The output current level or the motor torque level to output the BOF signal can be set individually for forward rotation and reverse rotation. Set the output current or the motor torque during reverse rotation in Pr.1408 Brake opening current for reverse rotation. (When Pr.1408 = "9999", the Pr.279 setting is applied to the operation even during reverse rotation.)
