The field containing the parameter “0” is not used for the spindle machine data..
Spindle configuration
Machine data for setpoint and actual values
Setpoints:
MD 30130 CTRLOUT_TYPE [AX4] = 1
Actual values:
MD 30200 NUM_ENCS[AX4] = 0 ;Spindle without encoder
MD 30200 NUM_ENCS[AX4] = 1 ;Spindle with encoder
MD 30240 ENC_TYPE[AX4] = 2

Example 1 for encoder matching:
Spindle with square–wave encoder (500 pulses) mounted directly on the spindle. The internal
multiplication = 4. The internal computational resolution amounts to 1,000 increments per de-
gree.

One encoder increment amounts to 180 internal increments. One encoder increment amounts
to 0.18 degrees (finest positioning possibility).
