404 Terminal 27 Stop (INPUT 27)
Value:
Motor Coasting Stop (MTR. COAST) [0]
Quick-Stop (Q-STOP) [1]
DC Braking (DC-BRAKE) [2]
★ Reset and Motor Coasting (RST & COAST) [3]
Stop (STOP=PRESS) [4]
Reset and Start (RST & START) [5]
Speed Down (SPEED DOWN) [6]
Digital Reference Select (SPEED SELECT) [7]
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.
[7]
Digital Reference Select
:
Together with parameter 402 you can choose between four
different digital references:
Terminal 18/27 Terminal 19
0 0 Digital reference 1
1 0 Digital reference 2
0 1 Digital reference 3
1 1 Digital reference 4
405 Terminal 29 Jog (TERMINAL 29 JOG)
Value:
★ Jog (JOG) [0]
Start (START) [1]
Digital Reference (DIGITAL REF.) [2]
Pulse Input, 100 Hz (PULSES 100 Hz) [3]
Pulse Input, 1 KHz (PULSES 1 KHz) [4]
Pulse Input, 10 KHz (PULSES 10 KHz) [5]
Setup Select (SETUP SELECT) [6]
Reset (RESET) [7]
Reversing (REVERSING) [8]
Speed Down (SPEED DOWN) [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.
