Description
Set the operation frequency of the DC injec-
tion 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 fre-
quency".
Holding function at stat 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 accel-
eration/deceleration time (initial value is
50Hz).
In addition, acceleration/deceleration time
can not be set separately.
