4. Commissioning
4.1. 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. 70 V DC
Residual voltage: < 5 %
Output current: 10 A nominal, 20 A peak
4.2. Function of the potentiometers
Potentiometer Function Turning ccw Turning cw
Gain Gain adjustment Decreasing Increasing
N max Maximum speed at set value of
10 V Decreasing speed Increasing speed
I max Current limitation Decreasing min. 0,3 A Increasing max 10 A
IxR IxR compensation low compensation High compensation
Offset adjustment n=0 at set value= 0 Motor turns cw Motor turns ccw
4.3. Presetting of potentiometers
Original delivered servo amplifiers are adjusted to uncritical values and for easy adjustment by the
user.
4.4. 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potentiometer ccw again, until the instability of the system is obsolete.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 = 0V and adjust potentiometer Offset until the motor stops
to speed 0.
IxR-control
DC-Tacho control
Digital-Encoder control
Voltage adjustment
Analog positioning
5. Additionally only at IxR compensation:
increase slowly Poti IxR, 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
