Description
20
Control command switching terminal
1
When the command source is set to terminal control (F0 - 02 =
1), this terminal can switch between terminal control and
keyboard control.
When the command source is set to communication control (F0
- 02 = 2), this terminal can switch between communication
control and keyboard control.
21
Acceleration and deceleration
prohibition
Ensure that the frequency inverter is not affected by external
signals (except shutdown command) and maintain the current
output frequency.
22
PID pause
The PID is temporarily disabled; the frequency inverter
maintains the current output frequency and no longer performs
PID adjustment of the frequency source.
23
PLC status reset
The PLC is suspended during the execution process. When the
PLC runs again, the frequency inverter can be restored to the
initial state of the simple PLC through this terminal.
24
The pendulum frequency suspended The frequency inverter outputs at the center frequency. The
frequency swing function is suspended.
25
Counter input
Input terminal of counting pulse.
26
Counter reset
The counter status is cleared.
27
Length count input
Input terminal for length count.
28
Length reset
Length zero clearing
29
Torque control prohibited
It is forbidden for the frequency inverter to carry out torque
control, and the frequency inverter enters the speed control
mode.
30
PULSE
（
Pulse) frequency input
( valid only for X5 )
X5 functions as a pulse input terminal.
31
Reserve
Reserve
32
Immediate DC braking
When this terminal is active, the frequency inverter switches
directly to the DC braking state
33
External fault normally closed input
When the normally closed signal of an external fault is sent to
the frequency inverter, the frequency inverter reports the fault
ETF and stops the operation.
34
Frequency modification prohibition
If this function is set to active, when the frequency changes, the
frequency inverter will not respond to the frequency change
until the terminal status is active.
35
The direction of PID action is
reversed
When this terminal is active, the direction of PID action is
opposite to the direction set by FA - 03
36
External parking terminal 1
When the keyboard is controlled, this terminal can be used to
stop the frequency inverter, which is equivalent to the function
of the STOP key on the keyboard.
37
Control command switching terminal
2
Used for switching between terminal control and
communication control. If the source is selected as terminal
control, the system will switch to communication control when
the terminal is active; on the contrary, it is also the opposite.
38
PID integral suspended
When this 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 switches to
preset frequency
If the terminal is valid, the frequency source X is replaced by a
preset frequency ( F0 - 09 )
40
Frequency source Y switches to
preset frequency
This terminal is valid, then the frequency source Y is replaced
by a preset frequency ( F0 - 09 )
