(1) How to change the highest frequency
(2) Adjusting the deviation of the highest frequency from the Pr. 38 (Pr. 39) setting.
(2)-1) Make adjustment with a voltage applied directly across terminals 2-5 (with a
current flowing across terminals 4-5)
(2)-2) Make adjustment at any point without a voltage applied across terminals
2-5 (without a current flowing across terminals 4-5)
Changing example When you want to use the 0 to 5VDC input frequency setting
POINT
Pr. 38 is an extended function parameter. Pr. 30 must be set to "1".
Change Pr. 38 "frequency setting voltage gain frequency" to 50Hz.
(1) How to change the highest frequency
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.

REMARKS
To change the value to more than 60Hz <50Hz>, Pr. 1 "maximum frequency" must
be set to more than 60Hz <50Hz>.
