• Terminal CA output [mA] = 20 [mA] × (Analog remote output value - 1000)/100
Where the output range is 0 to 20 mA.

• When Pr.158 AM terminal function selection = "87, 88, 89, or 90", an analog voltage can be output via terminal AM.
• Terminal AM output [V] = 10 [V] × (Analog remote output value - 1000)/100
The output range is -10 to +10 V regardless of the Pr.290 Monitor negative output selection setting.

 Analog remote output data retention (Pr.655)
• When the power supply is reset (including a power failure) while Pr.655 Analog remote output selection = "0" (initial
value) or 10" and, the remote analog output (Pr.656 to Pr.659) returns to its initial value (1000%).
• When Pr.655 = "1 or 11", the remote output data is stored in EEPROM before the inverter power is turned OFF. This means
that the signal output setting after power restoration is the same as that before the power was turned OFF. However, when
Pr.655 = "1", the data during an inverter reset (terminal reset or reset request via communication) is not saved.
• When Pr.655 = "10 or 11", the remote output data in the signal before the reset is stored even during an inverter reset.
• When the setting in Pr.655 is changed, the remote analog output (Pr.656 to Pr.659) returns to its initial value (1000%).
