Monitoring Reference (Pr. 55, Pr. 56) - Mitsubishi FR-E 500 Instruction Manual

4.2.21 Monitoring reference (Pr. 55, Pr. 56)

Pr. 55 "frequency monitoring reference"
Pr. 56 "current monitoring reference"
Set the frequency or current which is referenced
when the output frequency or output current is
selected for terminals FM and AM.

<Setting>
Refer to the above diagrams and set the frequency monitoring reference value in
Pr. 55 and the current monitoring reference value in Pr. 56.
(For 200V and 100V class inverters)
Pr. 55 is set when Pr. 54 = 0 and Pr. 56 is set when Pr. 54 = 1.
Set the Pr. 55 and Pr. 56 values so that the output pulse train output of terminal FM is
1440pulses/s.
Note: The maximum pulse train output of terminal FM is 2400pulses/s. If Pr. 55 is
not adjusted, the output of terminal FM will be filled to capacity. Therefore,
adjust Pr. 55.
(For 400V class inverter)
Refer to the above diagrams and set the frequency monitoring reference value in
Pr. 55 and the current monitoring reference value in Pr. 56.
Pr. 55 is set when Pr. 158 = 0 and Pr. 56 is set when Pr. 158 = 1.
In Pr. 55 and Pr. 56, set the frequency and current at which the output voltage of
terminal AM will be 10V.
Note: The maximum output voltage of terminal AM is 10VDC.
