 This parameter sets the status of the multi-function input signal (0: normally open; 1: normally
closed) and it is not affected by the status of SINK / SOURCE.
 bit 0–bit 6 correspond to MI1–MI7.
 The default for bit 0 (MI1) is FWD terminal, and the default for bit 1 (MI2) is REV terminal. You
cannot use this parameter to change the input mode when Pr.02-00 ≠ 0.
 You can change the terminal ON / OFF status through communications.
For example: MI3 is set to 1 (multi-step speed command 1) and MI4 is set to 2 (multi-step speed
command 2). Then the forward + second step speed command = 1001
2
= 9
10
.
 As long as Pr.02-12 = 9 is set through communications, there is no need to wire any multi-function
terminal to run forward with the second step speed.

 Use Pr.11-42 bit 1 to select whether the FWD / REV terminal is controlled by Pr.02-12 bit 0 and
bit 1.
