Multi-Function Input Mode Selection
0000h–FFFFh (0: N.O.; 1: N.C.)
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. If the
MI1 and MI2 are not used as two-wire / three-wire control method, set Pr.02-00 = 0. Then set
this parameter according to the functional requirements of terminals MI1 and MI2 (referring to
Pr.02-01 and Pr.02-02).
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 FWD / REV terminal is controlled by Pr.02-12 bit 0 and bit 1.
Multi-Function Output 1 (RY1)
Multi-Function Output 2 (MO1)
Multi-Function Output 3 (MO2)
2: Operation speed reached
3: Desired frequency reached 1 (Pr.02-22)
4: Desired frequency reached 2 (Pr.02-24)
5: Zero speed (Frequency command)
6: Zero speed including STOP (Frequency command)
7: Over-torque 1 (Pr.06-06–06-08)
8: Over-torque 2 (Pr.06-09–06-11)
10: Low voltage warning (Lv) (Pr.06-00)
11: Malfunction indication
13: Overheat warning (Pr.06-15)
14: Software brake signal indication (Pr.07-00)
15: PID feedback error (Pr.08-13, 08-14)
