Mitsubishi Electronics FR-S500 How to change the highest frequency, Mode indication

Explanation of functions (parameters)

<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)

Changingexample When you want to use the 0 to 5VDC input frequency setting potentiometer to change the 5V frequency from 60Hz(factory setting) 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.

(1) How to change the highest frequency

		Operation	Display
1. Confirm the RUN indication and operation			PU

mode indication.			EXT
The inverter must be at a stop.
The inverter must be in the PU operation mode.
(Press the	PU	.)
	EXT

2.Press the MODE to choose the parameter setting mode.

3. Turn the 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 shows the currently set value. (60Hz)

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

By turning the , you can read another parameter.

Press the SET to show the setting again.

Press the SET 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, Pr. 1 "maximum frequency" must be set to more than 60Hz.
