Functions
Analog Output AM Terminal
This function allows you to monitor the output frequency and current from the AM terminal on the
control terminal block (terminal).
•Analog voltage output from 0 to 10 V.
AM Selection
•Select a signal to output from the following table.
Output Frequency
Outputs the voltage according to the output frequency, with the maximum frequency being full scale.
This is intended for display indication and cannot be used as a line speed signal. Though the accu-
racy is ±5%, this could be exceeded depending on your meter.
Outputs a frequency obtained by multiplying the output frequency by the conversion coefficient
[b086], with the maximum frequency being full scale.
Output Current
Outputs a current value with 200% of the Inverter rated voltage being full scale.
The output method is the same as the output frequency. Monitor accuracy is ±10% at the halfway
point of base frequency.
AM Adjustment
•You can adjust the calibration of the analog voltage (0 to 10 V DC) from the AM terminal on the
control terminal block by using the Inverter setting.
Note: If the offset (C086) is changed, the point to reach 10 V changes accordingly because of par-
allel movement. To avoid this, adjust the offset (C086) before the gain (b080).
