7.1. Selection of power supply
Any power supply can be used as long the minimal requirements listed below are fulfilled. We
recommend to remove the motor from the mechanical construction to avoid damage and danger by
uncontrolled movements.
Requirements to the power supply:
Output voltage:
min. 11 V DC max. 30 V DC
Residual voltage:
< 5 %
Output current:
3 A nominal.

Motor turns ccw
7.3. Presetting of potentiometers
Original delivered servo amplifiers are adjusted to uncritical values and for easy adjustment by the
user.
7.4. Adjustment
1. Adjust max. set value (e.g. 10 V) and turn potentiometer
n max
cw til the
required speed is reached
2. Adjust potentiometer
Imax
to required value of current limitation.
Important
: Refer to motor manufacturers data sheet
3. Turn potentiometer
Gain
slowly cw until the required gain is reached
Important: If the motor turns rough, is vibrating or makes noise turn
potentiometer ccw again, until the instability of the system is obsolete.
4. Adjust set value = 0 V and adjust potentiometer
Offset
until the motor stops
to speed 0.
I x R-control
DC-Tacho control
Digital-Encoder control
5. Additionally only at I x R compensation:
increase slowly
Poti I x R
, until the value of the feedback is high enough to
control the drive to get best results concerning motor speed at different
loads
Torque control
1. Adjust potentiometer
Imax
to required value of current limitation.
Important
:: Refer to motor manufacturers data sheet
7.5. Commissioning
Select the required operating mode by setting the according jumpers on the left side of the unit. Refer
to the printing on the front plate. Required selection of:
•
operating mode
•
Input for set value
Connect motor, control inputs e.g. set value, enable and if necessary an additional encoder or tacho
to the drive.
Connect power supply.
Enabling and adjustment referring to manual.
