Mitsubishi FR - S500 OperationDisplay, How to change the highest frequency, Set value Hz

<Setting>

(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 potentiometer to change the 5V frequency from 60Hz to 50Hz

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.

OperationDisplay

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. (Press the EXTPU key.)

2.Press the MODE key to choose the parameter

setting mode.		MODE
3. Turn the setting dial	until the
parameter number 38 "frequency
setting voltage gain frequency" appears.
Pr. 30 must be set to "1".
(For the Pr. 30 setting method, refer to
the instruction manual (basic).)
4. Pressing the SET key shows the currently		SET
set value. (60Hz)

RUN

PU

EXT

The parameter number read previously appears.

5.	Turn the setting dial	to change
	the set value to "50.0". (50Hz)
6.	Press the SET key to set the value.		SET

Flicker ... Parameter setting complete!! 2

By turning the setting dial , you can read another parameter. Press the SET key to show the setting again.

Press the SET key twice to show the next parameter.

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 next page (2))

REMARKS

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