b6-01 Dwell Reference at Start
Setting Range:
0.0 to 400.0 Hz
Factory Default:0.0 Hz
Sets the dwell frequency reference during acceleration in units of 0.1 Hz.
b6-02 Dwell Time at Start
Setting Range:
0.0 to 10.0 Seconds
Factory Default:0.0 Seconds
Sets the amount of time that the frequency reference dwells during acceleration in units of 0.1 seconds.
b6-03 Dwell Reference at Stop
Setting Range:
0.0 to 400.0 Hz
Factory Default:0.0 Hz
Sets the dwell frequency reference during deceleration in units of 0.1 Hz.
b6-04 Dwell Time at Stop
Setting Range:
0.0 to 10.0 Seconds
Factory Default:0.0 Seconds
Sets the amount of time that the frequency reference dwells during deceleration in units of 0.1 seconds.
b7 Droop Control
The droop control function reduces the motor speed based on the load torque of the motor.
b7-01 Droop Control Level
Setting Range:
0.0 to 100.0%
Factory Default:0.0%
Sets the amount of speed reduction as a percentage of maximum output frequency E1-04 when the motor is producing 100% of
rated torque. The actual amount of motor speed reduction is based on the ratio of the amount of motor torque and the maximum
output frequency E1-04.
b7-02 Droop Control Delay Time
Setting Range:
0.03 to 2.00 Seconds
Factory Default:0.05 Seconds
Sets the response time in response to load changes. Decreasing this setting will cause the response to become quicker; however,
instability may occur.
