< Servo specification >
(Note 1) For the multiaxis drive unit, a control by each axis is not available.
It is required to turn the servo of all axes OFF in the drive unit in order to enable a motor brake output.
(Note 2) Always set L-axis as primary axis and M-axis as secondary axis for the speed command synchronous control using
MDS-D2-V3. Other settings cause the initial parameter error alarm.
