Description
Set the frequency when the motor
rated torque is generated. (50Hz/
60Hz)
Maximum inverter output voltage
95% of power supply voltage
Same as power supply voltage
Set the base frequency when the
RT signal is on.
Second V/f is invalid.
Set frequency when the RH signal
is on.
Set frequency when the RM signal
is on.
Set frequency when the RL signal
is on.
Frequency from 4 speed to 15
speed can be set according to the
combination of the RH, RM, RL
and REX signals.
9999: not selected
Set the motor acceleration time
* Initial values differ according to
the inverter capacity:
FR-D720S-008SC to 100SC
FR-D740-080SC or less/
FR-D740-120SC and 160SC
Set the motor deceleration time
* Initial values differ according to
the inverter capacity:
FR-D720S-008SC to 100SC
FR-D740-080SC or less/
FR-D740-120SC and 160SC
Set the frequency referenced as
acceleration/deceleration time. As
acceleration/deceleration time, set
the frequency change time from
stop to Pr. 20.
Set the acceleration/deceleration
time when the RT signal is on.
* Initial values differ according to
the inverter capacity:
FR-D720S-008SC to 100SC
FR-D740-080SC or less/
FR-D740-120SC and 160SC
Set the deceleration time when the
RT signal is on.
