All Modes
0: IP00 enclosure drive
2: IP00 enclosure drive with top protective cover
All Modes
Torque Boost increases the output current limit while decreasing the carrier frequency when the
output current exceeds a certain value.
0: Disabled
3: Enabled
All Modes
Sets the reduced carrier frequency used by the Torque Boost function.
All Modes
0: Disabled. L8-55 should be disabled when using a regen converter or an optional braking unit.
1: Protection enabled.
All Modes
Sets stopping method when a Input phase loss fault (PF) occurs. See parameter L8-05.
0: Ramp to Stop - Decelerate to stop using the deceleration ramp in C1-02.
1: Coast to Stop
2: Fast Stop - Decelerate to stop using the deceleration ramp in C1-09.
3: Alarm only - Drive continues operation.
All Modes
Used to suppress speed oscillations that occur with an unloaded motor and that have the same
frequency as the output frequency.
All Modes
0: Mode 0
1: Mode 1
V/f OLV
Sets the internal speed feedback detection control gain in the automatic frequency regulator
(AFR).
If hunting occurs, increase the set value. If response is low, decrease the set value.
V/f OLV
Sets the time constant used for speed feedback detection control (AFR).
V/f OLV
Sets the AFR time constant to be used during regen.
V/f OLV
0: Disabled
1: Enabled
V/f OLV
Sets the time required to accelerate the motor at 100% torque from 0 to the nominal speed.
