Detailed Description
47 Emergency stop
Upon an emergency, the AC drive decelerates to stop
within the deceleration time for emergency stop
specified by F8‑55. In V/f control mode, if the
deceleration time for emergency stop is 0s, the AC
drive decelerates to stop within the minimum unit
time. The 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 AC drive decelerates to stop regardless of the
command source (operation panel, terminal, or
communication). In this mode, the deceleration time is
fixed to deceleration time 4 (F8‑08).
49
Deceleration DC
braking
The AC drive decelerates to the DC braking start
frequency upon stop (F6‑11) before starting DC
braking.
50
Clear the current
running time
The terminal is used to clear the current running 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 the AC drive between
the two‑wire control mode and three‑wire control
mode.
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.
