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 modifcation
forbidden
After this terminal becomes ON
,
the AC drive does not
respond to any frequency modifcation
.
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

frequency source X and
preset frequency
After this terminal becomes ON
,
the frequency source X
is replaced by the preset frequency set in P0
-
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 P0
-
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
.

defned 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 P9
-
49
.
