Description
Adjusts the slip compensation function delay time.
Decrease the setting when the slip compensation response
is too slow, increase it when the speed is not stable.
Disabled when Simple V/f Control with PG (H6-01 = 3)
is used.
Sets the slip compensation upper limit. Set as a percentage
of motor rated slip (E2-02). Disabled when Simple V/f
Control with PG (H6-01 = 3) is used.
Selects slip compensation during regenerative operation.
0: Disabled
1: Enabled
Using the Slip Compensation function during
regeneration may require a braking option to handle
momentary increasing regenerative energy.
Selects if the motor magnetic flux is reduced during output
voltage saturation.
0: Disabled
1: Enabled
C4: Torque Compensation
Use C4 parameters to configure Torque Compensation function.
V/f Control: Sets the gain for the automatic torque
(voltage) boost function and helps to produce better
starting torque.
Increase this setting when using a long motor cable or
when the motor is significantly smaller than the drive
capacity.
Decrease this setting when motor oscillation occurs. Set
the value so that the current at low speed does not exceeds
the drives rated current.
Open Loop Vector: Sets the torque compensation function
gain. Normally no change is required.
Sets the torque compensation filter time.
Increase this setting when motor oscillation occurs.
Reduce the setting if there is not enough response from
the motor.
Sets torque compensation at forward start as a percentage
of motor torque.
Sets torque compensation at reverse start as a percentage
of motor torque.
Sets the time constant for torque compensation at forward
start and reverse start (C4-03 and C4-04). The filter is
disabled if the time is set to 4 ms or less.
Sets the torque compensation time 2. When an ov fault
occurs with sudden load changes or at the and of an
acceleration, increase the setting.
Note: Adjustment is not normally required. If adjusted
then AFR time 2 (n2-03) should be adjusted too.
C5: Speed Control (ASR)
Use C5 parameters to configure the Automatic Speed Regulator (ASR).
Sets the proportional gain of the speed control loop
(ASR).
Sets the integral time of the speed control loop (ASR).
Sets the speed control gain 2 of the speed control loop
(ASR).
Sets the integral time 2 of the speed control loop (ASR).
Sets the upper limit for the speed control loop (ASR) as a
percentage of the maximum output frequency (E1-04).
C6: Carrier Frequency
Use C6 parameters to configure the carrier frequency drive settings.
