● Use this parameter to set the response time of the digital input terminals MI1–MI7.
● This function is to delay and confirm the digital input terminal signal. The time for delay is also the time for
confirmation. The confirmation prevents interference that could cause error in the input to the digital terminals.
But in the meanwhile, it delays the response time though confirmation improves accuracy.

● The parameter setting is in hexadecimal.
● 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.
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 FWD / REV terminal is controlled by Pr.02-12 bit 0 and bit 1.
