Monitor terminal function

Monitor terminal function [FM] (analog)
• The inverter provides an analog output terminal primary for frequencymonitoring on terminal [FM]
(output frequency, Output current, output voltage and output power monitor signal).
•Parameter C18 selects the output signal data.
When using the analog motor for monitoring, use scale reactor C19 and C20 toadjust the [FM] output
so that the maximum frequency in the inverter corresponds to full-scale reading on the motor.
(1) output frequency monitor signal
The [FM] output varies with the inverter output frequency.
The signal on [FM] reaches full scale when the inverter outputs themaximum frequency.
Note) This is dedicated indicator, so that it cannot be used as a line speed signal.
The indicator accuracy after adjustment is about ±5%
(Depending on the meter, the accuracy may exceed this value)
(2) output current monitor signal
The [FM] output varies with the inverter output current to the motor.
The signal on [FM] reaches full scale when the inverter output current reaches 200% of the rated
inverter current.
(3) output voltage monitor signal
The [FM] output varies with inverter output voltage.
The signal on [FM] reaches full scale when the inverter output voltage reaches 100% of the rated
inverter voltage.
(4) output power monitor signal
The [FM] output varies with inverter output voltage.
The signal on [FM] reaches full scale when the inverter output power reaches 200% of the rated
inverter power.
The accuracy of the current reaches approximately ±10%
