*1
When Pr.59 Remote function selection ≠ "0", functions of the RL, RM, and RH signals are changed as shown in the table.
*2
The OH signal is activated when the relay contact is open.
NOTE
• The same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
• The priorities of the speed commands are defined as follows: JOG > multi-speed setting (RH, RM, RL, REX) > PID (X14).
• When the Inverter run enable (X10) signal is not assigned, the RT signal performs the same function.
• The same terminals are used to assign the multi-speed (7-speed) setting and the remote setting. The multi-speed setting and
the remote setting cannot be assigned separately.
• When the terminal assignment is changed with Pr.178 to Pr.182 (Input terminal function selection), wiring may be mistaken
due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming the function
of each terminal.

Inverter output shutoff

The inverter output can be shut off with the MRS signal. The logic of the MRS signal can also be selected.
