Chapter 6 P4 input terminal
terminal 2
communication control. If the command source is
selected as the terminal control, the system switches
to communication control when the terminal is valid;
vice versa.
38
PID integration pause
When the terminal is valid, the integral adjustment
function of the PID is suspended, but the proportional
adjustment and differential adjustment functions of the
PID are still valid.
39
Frequency source X and
preset frequency switching
When the terminal is valid, the frequency source X is
replaced by the preset frequency (P0-08).
40
Frequency source Y and
preset frequency switching
When the terminal is valid, the frequency source Y is
replaced by the preset frequency (P0-08).
43
PID parameter switching
When the terminal is invalid, the PID parameter uses
PA-05~PA-07; when the terminal is valid, PA-15~PA-
17 is used; (PA-18=1)
44
User-defined fault 1
When the user-defined faults 1 and 2 are valid, the
inverter will alarm ERR27 and ERR28 respectively,
and the inverter will select the action mode selected by
P9-49 according to the fault protection action.
45
User-defined fault 2
46
Speed control / torque
control switching
The inverter is switched between torque control and
speed control mode.
When the terminal is invalid, the inverter runs in the
control mode defined by A0-00. When the terminal is
valid, it switches to the other mode.
47
emergency stop
When the terminal is valid, the inverter stops at the
fastest speed, and the current is at the set current limit
during the stop.
This function is used when the inverter needs to stop
as soon as possible in an emergency state.
48
External parking terminal 2
In any control mode (panel control, terminal control,
communication control), this terminal can be used to
decelerate the inverter, and the deceleration time is
fixed at deceleration time 4.
49
Deceleration DC braking
When valid, the inverter decelerates to the braking
start frequency and then DC braking.
50
This run time is cleared
When the terminal is valid, the timing of the inverter
running this time is cleared. This function needs to be
used together with the timing operation (P8-42) and
the current running time arrival (P8-53).
