Monitor terminal function [AMI] (analog)
• The inverter provides an analog output terminal primary for frequencymonitoring on terminal [AMI]
(output frequency, Output current, output voltage monitor signal).
•Parameter C25 selects the output signal data.
When using the analog motor for monitoring, use scale reactor C26 and C27 toadjust the [AMI] output
so that the maximum frequency in the inverter corresponds to full-scale reading on the motor.
(1) output frequency monitor signal
The [AMI] output varies with the inverter output frequency.
The signal on [AMI] 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 [AMI] 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.
inverter output current (measured) : Im
monitor display current : Im'
inverter rated current : Ir
(3) output voltage monitor signal
The [AMI] output varies with inverter output voltage.
The signal on [AMI] reaches full scale when the inverter output voltage reaches 100% of the rated
inverter voltage.
(4) output power monitor signal
The [AMI] output varies with inverter output voltage.
The signal on [AMI] reaches full scale when the inverter output power reaches 200% of the rated
inverter power.
The accuracy of the current reaches approximately ±10%
