Remote Output Function - Mitsubishi Electric 800 Series Instruction Manual

Remote output function

The signal can be turned ON or OFF via the output terminal on the inverter as if the terminal is the remote output terminal for
a programmable controller.

 Remote output setting (REM signal, Pr.496, Pr.497)
• The signal assigned to each of the output terminal can be turned ON or OFF according to the settings of Pr.496 and Pr.497.
The signal assigned to each of the remote output terminal can be turned ON or OFF through communication.
• To use the Remote output (REM) signal, set "96" (positive logic) or "196" (negative logic) in any parameter from Pr.190 to
Pr.192 (Output terminal function selection) to assign the function to the terminal.
• Refer to the following figures to check correspondences between the bit and the actual terminal. When "1" is set in the bit
corresponding to the terminal to which the REM signal assigned by setting a number in Pr.496 and Pr.497 each, the signal
turns ON (or OFF in negative logic setting). Also, setting "0" allows the signal to turn OFF (or ON in negative logic setting).
• For example, when Pr.190 RUN terminal function selection = "96" (positive logic) and "1" (H01) is set in Pr.496, the REM
signal assigned to terminal RUN turns ON.

*1 Any value
*2 Y0 to Y6 are available by installing the output-extending option (FR-A8AY) or via communication.
*3 RA1 to RA3 are available by installing the relay output option (FR-A8AR) or via communication.
 Remote output data retention (REM signal, Pr.495)
• When the inverter power is reset (or a power failure occurs) while Pr.495 = "0 (initial value) or 10", the REM signal setting
is cleared. (The ON/OFF state of the signal assigned to each terminal is determined by the settings in Pr.190 to Pr.192.)
The settings in Pr.496 and Pr.497 are reset to "0".
• When Pr.495 = "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.495 = "1", the data during an inverter reset (terminal reset or reset request via communication) is not saved.
