Enter a value for the jog speed
n
JOG
, which is a xed output speed.
The frequency converter runs at
this speed when the jog function is
activated. The maximum limit is
dened in parameter 4-13 Motor
Speed High Limit [RPM].
See also parameter 3-11 Jog Speed
[Hz] and parameter 3-80 Jog Ramp

Congure the ramp times for each of the 2 ramps
(parameter group 3-4* Ramp 1 and parameter group 3-5*
Ramp 2).

NOTICE
If [1] S-ramp Const Jerk is
selected and the reference
during ramping is changed,
the ramp time may be
prolonged to realize a jerk-free
movement, which may result
in a longer start or stop time.
Extra adjustment of the S-
ramp ratios or switching
initiators may be necessary.
Select the ramp type, depending on
requirements for acceleration/
deceleration.
A linear ramp gives constant
acceleration during ramping. An S-
ramp gives non-linear acceleration,
compensating for jerk in the
application.
