Parameter overview

Parameter 160 is factory set to "9999". That means that only the parameters marked with
the following table are accessible. Set parameter 160 to "0" to access other or all parameters.
The half-tone screened parameters allow its setting to be changed during operation even if "0"
(initial value) is set in Pr. 77 "Parameter write selection".

Description
Set the output voltage at 0Hz as %
* Initial values differ according to
the inverter capacity:
Initial

00023 6%
00038–00083 4%
00125/00170 3%
00250–00770 2%
00930/01160 1.5%
01800 or more 1%
Set the torque boost when the RT
signal is on.
Without second torque boost
Set the upper limit of the output
frequency
* The setting depends on the
inverter capacity:
(01160 or less/01800 or more)
Set the lower limit of the output
frequency
Set when performing operation at
120Hz or more
* The setting depends on the
inverter capacity:
(01160 or less/01800 or more)
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.
