POINT
•Pr. 38 is an extended function parameter. Pr. 30 must be set to "1".
(Refer to page 48.)
•Change Pr. 38 "frequency setting voltage gain frequency" to 50Hz.
(1) -1) Changing the highest frequency (0 to 5V input)
Operation
1.
Confirm the RUN indication
and operation mode indication.
The inverter must be at a stop.
The inverter must be in
the PU operation mode.
2.
Press the to choose
MODE

3.
Turn the until
Pr. 38 "frequency setting
voltage gain frequency" appears.
Pr. 30 must be set to "1"
(Refer to steps 3 to 6 on
page 48 for the parameter
setting method.)
4.

The monitor/frequency setting indication cannot be changed to just
50Hz ...Why?
The calibration parameter C4 "frequency setting voltage gain" value must
be set. (Refer to page 42.)
REMARKS
To change the value to more than 60Hz, Pr. 1 "maximum frequency" must be set to more than
60Hz.
When you want to use the 0 to 5VDC input frequency
setting potentiometer to change the 5V-time frequency
from 60Hz (factory setting) to 50Hz.
