Full-scale value when current monitor value is
output to terminal AM.
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 162)
* The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in

.
(1) Frequency monitoring reference (Pr. 55)
• Set the frequency when the optional frequency meter (DC voltmeter
10VDC) shows 60Hz or 120Hz (shows full scale) which is connected
to the terminal AM and 5.
• Set the frequency (output frequency/set frequency) when the voltage
output at terminal AM is 10VDC.
• The analog voltage output and frequency at terminal AM are
proportional. (The maximum output voltage is 10VDC.)
(2) Current monitoring reference (Pr. 56)
• Set the current to be referenced when the current monitor (inverter
output current, etc.) is selected for terminal AM display.
• Set the current value when the voltage output at terminal AM is
10VDC.
• The analog voltage output and current value at terminal AM are
proportional. (The maximum output voltage is 10VDC.)
