404 Terminal 27 Stop (INPUT 27)
Value:
Motor Coasting Stop (MTR. COAST)

Function:
Using this parameter (terminal 27) you can give the motor
various stop signals.
Description:
[0]
Motor coasting stop:
If 0 V is applied to terminal 27 the motor will coast to a stop.
[1]
Quick Stop:
If 0 V is applied to terminal 27 the motor will brake to a stop
according to the ramp-down time set in parameter 218.
A DC current brakes the motor after ramping down to 0,
according to the setting of parameters 306-308.
[2]
DC Brake:
If 0 V is applied to terminal 27 the motor will brake to a stop
according to the settings of parameters 306 and 308.
[3]
Reset and Motor Coasting:
If 0 V is applied to terminal 27 the motor will start coasting
and the VLT adjustable frequency drive is reset.
[4]
Stop = Press:
A circuit breaker between terminals 12 and 27, when
opened briefly causes ramp-down to stop.
[5]
Reset and Start:
This can be used as a start function when you use
terminals 18 and 19 to select a digital reference. 24 V
applied to terminal 27 will make the adjustable frequency
drive reset and the motor ramp up to the set reference
according to the ramp-up time set in parameter 215.
[6]
Speed Down:
This is used together with parameter 230. It is possible to
make the output frequency drop towards f
MIN
, as long as 24
V is applied to terminal 27.
At 0 V applied to terminal 27, the output frequency in
question is maintained. Also refer to parameter 402.

Digital Reference Select:
Together with parameter 402 you can choose between four
different digital references:

[9]
Function:
Using this parameter (terminal 29) you can give the motor
different jog signals.
Description:
You can set the output frequency to a pre-programmed
value (jog in parameter 203). Recording Digital reference
you can enable/disable values stored in parameters 205-
208.
If terminal 29 is used for either pulse signal reference (open
loop) or pulse signal feedback (closed loop) choose one of
the pulse inputs [3] - [5].
If Multi Setup is selected in parameter 001, the terminal can
be used to switch between setups 1 and 2.
