Description
39
Normally closed (NC) input of
external fault
After this terminal becomes ON, the frequency inverter reports Err15
and performs the fault protection action. For more details, see the
description of bb-32.
40
User-defined fault 1
If these two terminals become ON, the frequency inverter reports
Err27 and Err28 respectively, and performs fault protection actions
based on the setting in bb-34.
41
User-defined fault 2
42
RUN pause
The frequency inverter decelerates to stop, but the running parameters
are all memorized, such as PLC, swing frequency and PID parameters.
After this function is disabled, the frequency inverter restore to its
status before stop.
43
Free stop
The frequency inverter stops its output, the motor free stop and is not
controlled by the frequency inverter. It is the same as free stop
described in b1-07.
44
Emergency stop
When this terminal becomes ON, the frequency inverter stops within
the shortest time. During the stop process, the current remains at the
set current upper limit. This function is used to satisfy the requirement
of stopping the frequency inverter in emergency state.
45
External STOP terminal 1
In operation keypad mode, this terminal can be used to stop the
frequency inverter, equivalent to the function of the STOP key on the
operation keypad.
46
External STOP terminal 2
In any control mode (operation panel, terminal or communication), it
can be used to make the frequency inverter decelerate to stop. In this
case, the deceleration time is deceleration time 4.
47
Deceleration DC braking
When this terminal becomes ON, the frequency inverter decelerates to
the initial frequency of DC braking and then switches over to DC
braking state.
48
Immediate DC braking
After this terminal becomes ON, the frequency inverter directly
switches over to the DC braking state.
49
Clear this time running time
When this terminal becomes ON, the frequency inverter's this time
running time is cleared. This function must be supported by b2-28 and
b2-31.
The four multi-function terminals have 16 state combinations, corresponding to 16 reference values, as listed in the
following table.

If the frequency source is multi-speed function, the value 100% of C1-00~ C1-15 corresponds to the value of b0-13
(Maximum frequency).
Besides as the multi-speed function, the multi-function terminals can be also used as the PID setting source or the
