Parameter Groups
‑153‑
47: Emergency stop
When the system is in the emergency state, the AC drive decelerates according to
F8‑55 (Terminal deceleration time for emergency stop). When the deceleration
time for emergency stop is 0s in V/f mode, the AC drive decelerates according to
the minimum unit time. The input terminal does not need to be kept in the closed
state. Even if it stays closed only for a short moment, the AC drive will come to an
emergency stop. Different from general deceleration, if the emergency stop input
terminal is opened after the deceleration time for emergency stop expires and the
running signal is still active on the AC drive terminal, the AC drive will not restart.
To restart the AC drive in this case, disconnect the running terminal and input the
running command.
48: External stop terminal 2
The terminal is used to make the AC drive decelerate to stop in any control mode
(operating panel, terminal, or communication control). In this case, the
deceleration time is fixed to deceleration time 4 (F8‑08).
49: Deceleration DC braking
The AC drive decelerates to F6‑11 (Shutdown DC injection braking start frequency)
and then enters the DC braking state.
50: Clear the current running time
The terminal is used to clear the current operation time of the AC drive. If the
current running time is less 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 greater than the set value (greater than 0) of
F8‑53, and the terminal is active, the current running time is not cleared.
51: Two‑wire/Three‑wire control switchover
The terminal is used to switch between two‑wire control and three‑wire control.
When F4‑11 is set to 0 (Two‑wire mode 1) and the terminal is active, the AC drive
switches to three‑wire mode 1. When the terminal is inactive, two‑wire mode 1 is
used.
When F4‑11 is set to 1 (Two‑wire mode 2) and the terminal is active, the AC drive
switches to three‑wire mode 2.
When F4‑11 is set to 2 (Three‑wire mode 1) and the terminal is active, the AC drive
switches to two‑wire mode 1.
When F4‑11 is set to 3 (Three‑wire mode 2) and the terminal is active, the AC drive
switches to two‑wire mode 2.
52: Electromagnetic shorting
When the terminal is active, the AC drive enters the electromagnetic shorting
state.
53 Thickness overlaying
When the roll diameter is calculated based on accumulative thickness, this
terminal records the number of revolutions.
