Setting for Rampup time and Rampdown time
By separate menus for Rampup time and Rampdown time an adjustment is possible to individual
system conditions.
This function is switched behind the actual controller function.
Rampup time
Rampup time
Time setting in which the automatic controller output from 0 % to 100 % rises.
Setting range: 2...250 sec.
Factory setting: 10 sec.
Rampdown time
Rampdown time
Time setting in which the automatic controller output from 100 % to 0 % reduces.
Setting range: 2...250 sec.
Factory setting: 20 sec.

Setting Rolling direct.
Attention!
The direction of rotation of the motor must be checked during initial commissioning (
arrow). We will not under any circumstances provide a guarantee for damage due to incorrect
motor direction of rotation!
When connected in accordance with the connection diagram, the standard rotary direction
“
RIGHT
”
results under factory settings. A change of direction is feasible by exchanging the phase sequence in
the motor connection or through reprogramming.
Rolling direct.
By selection of the parameter
“
Direction of rotation
”
and
following pressing the
P
key, the direction of rotation can
changed to
“
L
”
for anti-clockwise direction of rotation. (factory
setting
“
R
”
).
Pressing the
P
key causes the value that has been set to be
accepted.
Rolling direct.
If the rotary direction is reversed with an available modulation, it is initially reduced to
“
0
”
(discon-
nected) and subsequently increased back to the default value.

Setting Current limit
DC Current limit
The frequency inverter uses current limitation as an additional safety feature. It can be
adapted as necessary. When the motor
’
s rated current is exceeded by the percentage
set here, the modulation is reduced as far as necessary until it has readjusted itself.
This prevents overloading the motor.
Setting range: 100...200 %
Factory setting: 160 %

Active current limit is signaled by a bright triangle in the display
