402 Terminal 18 Start (Input 18); Pulse Start; Speed Up; Digital Reference Select - Danfoss VLT 2000 Series Manual

402 Terminal 18 start (INPUT 18)

Value:
Start (START)
Pulse start (LATCH START)
No function (NO OPERATION)
Speed up (SPEED UP)
Digital reference select (SPEED SELECT)
Reversing (REVERSING)
Reset and start (RESET&START)
Motor coasting and start (COAST/START)
Function:
Using this parameter (terminal 18) you can give the
motor various start signals.
Description:
Start:
24 V on terminal 18 will make the motor ramp up to
the set reference. 0 V will make the motor ramp down
to stop.

Pulse start:

On selection of Press cont. in parameter 402 and
application of a pulse (24 V) to terminal 18, the motor
wll ramp up to the set reference. Further pulses do
not have any effect. Therefore the motor must be
stopped via terminal 27 (parameter 404)
No function:
Locks the input.

Speed up:

This is used together with parameter 230. It is
possible to make the output frequency increase
towards f as long as 24 V is applied to terminal 18.
MAX
At 0 V on terminal 18 the output frequency in
question is maintained. See also parameter 403.

Digital reference select:

Together with parameter 403 you can choose
between four different digital references:
18/27 19 Terminal
0 0 Digital reference 1
1 0 Digital reference 2
0 1 Digital reference 3
1 1 Digital reference 4
= Factory setting. Text in ( ) = Display text. The figures in [ ] are used in bus communication.

Reversing:
[0] If the motor reverses when 24 V is applied to terminal
[1]
18, it will change direction again when 0 V is applied
[2]
to the terminal.
[3]
[4]
Reset and start:
[5]
The function can be used as start when terminals 27
[6]
and 19 are used to select between the digital
[7]
references and terminal 29 to change setup (8 digital
speeds). 24 V applied to terminal 18 resets the VLT
frequency converter and the motor ramps up to the
set reference according to the ramp-up time set in
parameter 215.
Motor coasting and start:
24 V applied to terminal 18 makes the motor ramp up
to the set reference.
0 V applied to terminal 18 sets the motor to coasting,
running freely until it stops. This can be used in
connnection with a mechanical brake.
