Detailed Description
37
Control command
switchover terminal
2
The terminal is used to switch the AC drive between
terminal control and communication control.
If the running command source is set to terminal
control, the system switches to communication control
when this terminal is active.
If the running command source is set to
communication control, the system switches to
terminal control when this terminal is active.
38
PID integral pause The PID integral adjustment function is paused.
However, the PID proportion adjustment and
differential adjustment functions are still available.
39
Switchover between
main frequency and
preset frequency
This parameter is used to switch from the main
frequency to the preset frequency (F0‑08).
40
Switchover between
auxiliary frequency
and preset frequency
This parameter is used to switch from the auxiliary
frequency to the preset frequency (F0‑08).
41
Motor selection The terminal is used for motor selection. When the
terminal is active, motor 2 is selected. When the
terminal is inactive, motor 1 is selected.
42
Position lock When the terminal is active, the AC drive decelerates to
0 Hz and then enters the position lock state.
43 PID parameter
switchover
With the PID parameter switchover condition set to
"switchover by DI" (FA‑18 = 1), when the terminal is
inactive, the PID parameters are FA‑05 to FA‑07
(proportional gain Kp1, integral time Ti1, and
derivative time Td1). When terminal is active, the PID
parameters are FA‑15 to FA‑17 (proportional gain Kp2,
integral time Ti2, and derivative time Td2).
44
User‑defined fault 1 The AC drive reports the E27.00 alarm and proceeds
according to the value of F9‑49 (fault protection action
selection).
45
User‑defined fault 2 The AC drive reports the E28.0 alarm and proceeds
according to the value of F9‑49 (fault protection action
selection).
46
Speed control/
torque control
switchover
The AC drive is switched between the speed control
mode and the torque control mode.
If 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.
If 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.
