Description
Set the rated motor current.
Made valid when the RT signal is
on. Set the rated motor current.
Second electronic thermal O/L
relay invalid
Set the level (resistance value) for
PTC thermistor protection acti-
vates.
PTC thermistor protection is
inactive.
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-D720S-008SC and 014SC/
FR-D720S-025SC or more,
FR-D740-012SC or more
Starting frequency can be set.
Set the holding time of Pr. 13
"Starting frequency".
Holding function at stat is invalid.
For constant torque load
For variable-torque load
at reverse rotation
boost of 0%
For constant
torque eleva-
tors
at forward rota-
tion 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 accelera-
tion/deceleration time (initial value
is 50Hz).
In addition, acceleration/decelera-
tion time can not be set separately.
