Description
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.
Selects the load rating for the drive.
0: Heavy Duty (HD) for constant torque applications.
1: Normal Duty (ND) for variable torque applications.
This setting affects the Rated output current and overload
tolerance of the drive.
Selects the carrier frequency
