Operating Instructions
6.2
Adjustments potentiometer P8 I
cont
and current limit mode DIP switch S6
It is standard that a maximum current limiter is activated (DIP switch
S6
OFF).
In this way the motor current is limited to the value set on potentiometer
P4
I
max
(0.5 ... 10 A).
If DIP switch
S6
is turned to ON, a cyclical current limiter is also activated. This
current limiter method makes a certain level of motor protection against thermal
overload possible.
For 0.1 seconds the motor current is limited to the value set on potentiometer
P4
I
max
(0.5 ... 10 A) and then for 0.9 seconds current is limited to the value set
on potentiometer
P8
I
cont
(0.5 ... 10 A). After one second the cycle will repeat it-
self.
Pre-adjustment
P8
I
cont
= 50%.

Note
To achieve good control characteristics, encoders with low impulse counts per
turn should be run with the DIP switch
