Value Function Description
29 Torque control prohibited
The AC drive is prohibited from torque control and
enters the speed control mode.
30
Pulse input (enabled only
for DI5)
DI5 is used for pulse input.
31 Reserved Reserved.
32 Immediate DC braking
After this terminal becomes ON, the AC drive directly
switches over to the DC braking state.
33
Normally closed (NC) input
of external fault
After this terminal becomes ON, the AC drive reports
Err15 and stops.
34
Frequency modication
forbidden
After this terminal becomes ON, the AC drive does not
respond to any frequency modication.
35
Reverse PID action
direction
After this terminal becomes ON, the PID action direction
is reversed to the direction set in FA-03.
36 External STOP terminal 1
In operation panel mode, this terminal can be used to
stop the AC drive, equivalent to the function of the STOP
key on the operation panel.
37
Command source
switchover terminal 2
It is used to perform switchover between terminal
control and communication control. If the command
source is terminal control, the system will switch over to
communication control after this terminal becomes ON.
38 PID integral pause
After this terminal becomes ON, the integral adjustment
function pauses. However, the proportional and
differentiation adjustment functions are still valid.
39
Switchover between main
frequency source X and
preset frequency
After this terminal becomes ON, the frequency source X
is replaced by the preset frequency set in F0-08.
40
Switchover between
auxiliary frequency source
Y and preset frequency
After this terminal is enabled, the frequency source Y is
replaced by the preset frequency set in F0-08.
41 Motor selection terminal 1
Switchover among the four groups of motor parameters
can be implemented through the four state combinations
of these two terminals.
42 Motor selection terminal 2
43 PID parameter switchover
If the PID parameters switchover performed by means
of DI terminal (FA-18 = 1), the PID parameters are FA-
05 to FA-07 when the terminal becomes OFF; the PID
parameters are FA-15 to FA-17 when this terminal
becomes ON.
44 User-dened fault 1
If these two terminals become ON, the AC drive reports
Err27 and Err28 respectively, and performs fault
protection actions based on the setting in F9-49.
45 User-dened fault 2
46
Speed control/Torque
control switchover
This terminal enables the AC drive to switch over
between speed control and torque control. When this
terminal becomes OFF, the AC drive runs in the mode
set in A0-00. When this terminal becomes ON, the AC
drive switches over to the other control mode.
