Inovance MD520 Series Commissioning Guide

Commissioning and Trial Run
‑80‑
49: Decelerate to DC braking
The terminal is used to make the AC drive decelerate to the start frequency of DC
braking for stop (F6‑11) and then enter the DC braking state.
50: Clear the current running time
The terminal is used to clear the current running time of the drive.
● If the current running time is shorter than the set value (greater than 0) of F8‑53
(Current running time reached) and the terminal is active, the current running
timing is cleared.
● If the current running time is longer than the set value (greater than 0) of F8‑53
(Current running time reached) and the terminal is active, the current running
timing is not cleared.
51: Two‑wire/Three‑wire control mode switchover The terminal is used to switch the
AC drive between the two‑wire control mode and three‑wire mode.
● When F4‑11 is set to 0 (two‑wire control mode 1) and the terminal is active, the
drive switches to three‑wire control mode 1. When the terminal is inactive, two‑
wire control mode 1 is used.
● When F4‑11 is set to 1 (two‑wire control mode 2) and the terminal is active, the
drive switches to three‑wire control mode 2. When the terminal is inactive, two‑
wire control mode 2 is used.
● When F4‑11 is set to 2 (three‑wire control mode 1) and the terminal is active, the
drive switches to two‑wire control mode 1. When the terminal is inactive, three‑
wire control mode 1 is used.
● When F4‑11 is set to 3 (three‑wire control mode 2) and the terminal is active, the
drive switches to two‑wire control mode 2. When the terminal is inactive, three‑
wire control mode 2 is used.
52: Reverse running inhibited
When the terminal is active, even if the reverse frequency is set, the actual frequency
of the AC drive is fixed to 0. This function is the same as F8‑13 (Reverse frequency
inhibited).
64: Forward limit switch
65: Reverse limit switch
66: Water cooling fault input
When the external signal is sent to the drive and the terminal is active, Err64 is
reported.
67: Low liquid fault input
When the external signal is sent to the drive and the terminal is active, warning 66
(thousands position of F9‑50 = 2) or Err66 (thousands position of F9‑50 = 0) is
reported.
68 to 69: Reserved
