Setting instructions control

Please find below a description to set the operating parameters, if required after replacement
of the control and of the motor.

Vmax

This is the potentiometer to set the maximum possible speed of the motor.

The speed of 3000 min

-1

 must not be exceeded since the spindle bearings and your tools

might get damaged.

Vmin

This is the potentiometer to set the minimum possible speed of the motor. Make sure that the
speed does not fall below 50 min

-1

.

With reduced speed also the torque (power of the motor) and the cooling will reduce!

Torque

This is the potentiometer to set the torque when readjusting the motor. Depending on the
application set the value by which the the control will readjust. If you require less
readjustment, turn the potentiometer one to two turns in direction "minus". For a larger
readjustment, turn the potentiometer in direction "plus". For thread cutting we recommend
little torque.

Slope

This is the potentiometer to set the acceleration time of the motor at the moment when it
starts turning. If you require a smoother ramp, turn the potentiometer in direction "plus". In
order to achieve a steeper ramp, turn the potentiometer in direction "minus".

CL

This is the potentiometer to set the current limiting as an overload protection for the motor.
The current limiting is set by the manufacturer and must not be changed in any way.

General information

The control is charged with high constant-voltage currencies. Please make imperatively sure
that the housing will only be opened up in the idle status. Furthermore, make sure that any
settings are only being performed when the housing is closed. 

The spindle trimmers of the potentiometer are designed with 12 gears. This means in order to
achieve the corresponding minimum or maximum value, the spindle trimmer needs to be
turned 12 times. Due to this high number of gears of the spindle trimmer it is possible to
perform a very sensitive setting over the corresponding potentiometer.
