To solve monitoring problems, set the following machine data:
Parameterization example
Stepper motor frequency
Supplementary conditions
Servo gain
Max. stepper motor frequency
PLC interface signals when using a stepper motor in the controlled mode
4-36
Number Description
36000 Exact positioning coarse
36010 Exact positioning fine
36020 Delay exact positioning fine 1.0
36060 Maximum

Motor speed:
MD 30130
MD 30240
MD 31400
MD 32260
MD 32000
The parameterization is carried out using the machine data, which have
already been mentioned, after POWER–ON.
The resulting stepper motor frequency is displayed with machine data MD
31350.
Motor speed [rpm] • steps per stepper motor revolution
MD 31350 [Hz]= ------------------------------------------------------------------------------
This frequency must correspond to MD 32000.
The default setting of the servo gain when controlling stepper motors without
measuring system is K
The max. permissible stepper motor frequency is 500 kHz.
When using a stepper motor as an axis (spindle), the PLC interface signals
have to be used as follows:
The "Servo enable" signal provided via the NC will not be used to turn off the
drive ("Drive Enable" is always active). This pertains to the following signals:
