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 Time.
3.5.3 3-4* Ramp 1
Congure the ramp times for each of the 2 ramps
(parameter group 3-4* Ramp 1 and parameter group 3-5*
Ramp 2).

Enter the ramp-up time, that is the
acceleration time from 0 RPM–
parameter 1-25 Motor Nominal Speed. Select a
ramp-up time such that the output current
does not exceed the current limit in
parameter 4-18 Current Limit during ramping.

parameter 1-25 Motor Nominal Speed–0 RPM.
Select a ramp-down time preventing
overvoltage from arising in the inverter due
to regenerative operation of the motor. The
ramp-down time should also be long
enough to prevent that the generated
current exceeds the current limit set in
