Parameter Groups
‑332‑
39: Switchover between main frequency reference X and preset frequency
Used to switch from main frequency reference X to F0‑08 (Preset frequency).
40: Switchover between auxiliary frequency reference Y and preset frequency
Used to switch from auxiliary frequency reference Y to F0‑08 (Preset frequency).
41: Reserved
42: Position lock enabled
When the terminal is active, the AC drive decelerates to 0 Hz and then enters the
position lock state.
43: PID parameter switchover
If PID parameters are switched over through the DI terminal (FA‑18 = 1), the
following conditions are true. When the terminal is inactive, the PID parameters
are FA‑05 to FA‑07 (proportional gain Kp1, integral time Ti1, and differential time
Td1). When the terminal is active, the PID parameters are FA‑15 to FA‑17 (PID gain
Kp2, integral time Ti2, and differential time Td2).
44: User‑defined fault 1
When the AC drive reports Err27, the AC drive will take measures according to the
value of F9‑49 (Fault protection action selection).
45: User‑defined fault 2
When the AC drive reports Err28, the AC drive will take measures according to the
value of F9‑49 (Fault protection action selection).
46: Speed control/Torque control switchover
The terminal is used to switch between speed control and torque control.
When A0‑00 (speed/torque control mode) is set to 0, the torque control mode is
used when the terminal is active, and the speed control mode is used when the
terminal is inactive.
When A0‑00 (speed/torque control mode) is set to 1, the speed control mode is
used when the terminal is active, and the torque control mode is used when the
terminal is inactive.
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 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.
