4.3.3.2 Continuous Current
Leave P2 in the position determined as described above, adjust P5 with five turns from left
stop.
Once again, move the motor with minimum speed to a mechanical stop and leave the set
value at the amplifier so that the motor still tries to move towards the stop. Neither limit
switch, nor I
AB
must be active.
After expire of the pulse current phase, the current is automatically reduced to the
continuous current, adjustable at P5. For adjusting P5, always turn slowly. After a short time
the new continuos current flows.
Adjustment becomes essentially easier when instead of the motor, three wye-connected
reactors are connected to the motor connections. The reactors should have a minimum
load inductance and a saturation current, that exceeds the maximum current of the
amplifier.
4.3.4 Setting the Maximum Motor Speed
The amplifier is set ex factory to a motor speed of max. = 3000 with 10V input voltage for
our motors. In order to reduce the maximum motor speed, turn the input potentiometer to
the left, to increase the motor speed turn it to the right.
4.3.5 Offset Adjustment of the Speed Regulator
The offset adjustment has to be carried out in a warm operating status of the device.
Define the set value zero (short-circuit the input). Adjust motor drift by setting P4 to zero.
