Motor Coasting & Start (COASTING/START)
[7]
Function:
This parameter gives the motor various start signals.
Description:
[0]
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.
[1]
Pulse Start:
On selection of Press Cont. in parameter 402 and
application of a pulse (24 V) to terminal 18, the motor will
ramp up to the set reference. Futher pulses do not have
any effect. (Therefore the motor must be stopped via
terminal 27 (parameter 404).
[2]
No Function:
Locks the input.
[3]
Speed Up :
This is used together with parameter 230. It is possible to
make the output frequency increase towards fMAX as long
as 24 V is applied to terminal 18.
At 0 V on terminal 18 the output frequency is maintained.
Also refer to parameter 403).

Digital Reference Select:
Together with parameter 403 you can choose between four
different digital references:
Terminal 18/27
Terminal 19

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

Function:
Using this parameter (terminal 19) you can e.g. change the
motor's direction.
Description:
[0]
Reversing:
Reverses the motor, when 24 V is applied to terminal 19
and changes the rotation direction again when 0 V is
applied to the terminal.
[1]
Start Reversing:
Reverses the motor, when 24 V is applied to terminal 19.
The motor stops when 0 V is applied to the terminal.
[2]
No Function:
Locks the input.
[3]
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 19.
At 0 V applied to terminal 19, the output frequency in
question is maintained. Also refer to parameter 402.
