The figures in [ ] are used in bus communication.
Function:
Used to select between different function
options for terminal 29.
Description of choices:
Jogging: Selected if the output frequency is
to be set to the preprogrammed value in
parameter 203. No separate start com-
mand to activate jogging is required.
Freeze jogging reference: Selected if
terminals 32/33 (parameter 406) are to be
used for digital speed control UP/DOWN,
with the jogging speed as the basis.
Logical “1” on terminal 29 will freeze the
jogging reference and the speed can be
changed with the help of terminal 32/33
(parameter 406 = speed UP/DOWN).
Freeze reference: Selected to use termi-
nals 32/33 (parameter 406) for digital
speed control UP/DOWN (motor
potentiometer). Logical “1” on terminal 29
will freeze the current reference, and the
speed can be changed using terminal 32/
33 (parameter 406 = speed UP/DOWN).
Digital reference: Selected to either select
one of the digital references (parameters
205-208) or other references (analogue
voltage parameter 412, current parameter
413), pulses (parameter 401), bus refer-
ence (parameter 516).
Digital reference functions only if “external
to/from” has been selected in parameter
204. When the digital reference is acti-
vated, the speed direction is determined
exclusively by the reference sign.
Ramp selection:
Different ramp times can be selected using
terminal 29:
Terminal 29 = “0” - Ramp 1 (para. 215/
216).
Terminal 29 = “1” - Ramp 1 (para. 217/
218).
The selected ramp UP/DOWN times apply
on START/STOP via terminal 18 (19 if
programmed) and if the reference is
changed.
Selection of Quick Stop via terminal 27 will
automatically activate ramp-down time 2
(para. 218).
