Description
Set the operation frequency of the DC
injection brake.
DC injection brake disabled
Set the operation time of the DC injection
brake.
DC injection brake disabled
Set the DC injection brake voltage (torque).
* Initial values differ according to the inverter
capacity:
FR-E720S-008SC and 015SC/
FR-E720S-030SC to 110SC,
FR-E740-016SC to 170SC/
FR-E740-230SC and 300SC
Starting frequency can be set.
Set the holding time of Pr. 13 "Starting
frequency".
Holding function at start is invalid.
For constant torque load
For variable-torque load
at reverse rotation
boost of 0%
For constant
torque elevators
at forward rotation
boost of 0%
Set the frequency for jog operation.
Set the acceleration/deceleration time for
jog operation. Set the time taken to reach
the frequency set in Pr. 20 "Acceleration/
deceleration reference frequency" for
acceleration/deceleration time (initial value
is 50 Hz).
In addition, acceleration/deceleration time
can not be set separately.
