•
Configure the spindle actual-value encoder as the 2nd encoder of an additional
digital drive. To do this, set the drive assignment of the actual value in the
same way as for the axis to whose Motor Module, for example, an SMC30 is
connected:
–
MD30220[0] ($MA_ENC_MODULE_NR[0]) = MD30220[0] of the digital
drive
•
The input assignment of the actual value should be set to the input for the
2nd encoder on the digital Motor Module:
–
MD30230[0] ($MA_ENC_INPUT_NR[0]) = 2
•
You can activate automatic drift compensation for a connected spindle actual
value encoder:
–
MD36700 ($MA_DRIFT_ENABLE)
A basic drift value is continuously entered as additional speed setpoint
irrespective of whether there is a spindle actual-value encoder:
–
MD36720 ($MA_DRIFT_VALUE)
