2-4-3 Connecting the synchronous control system
The connection method and motor/encoder type (SV025) setting combinations for each synchronous
control system are shown in the table below. For power supply connections for each servomotor type,
refer to "2-4-1 Connecting the servomotor".
Semi-closed system
(Only for motor side detector)
Full-closed system
(For machine side detector + motor side detector)
Position command
synchronous control
The operation is controlled with position commands from the NC, so there are no special
connections.
A normal value is set for the SV025 setting.
(1) When using MDS-C1-V1 drive
unit
(3) When using MDS-C1-V1 drive unit
(Only compatible with serial output linear scale)
Speed command
synchronous control
Current command
synchronous control
(2) When using MDS-C1-V2 drive
unit
MDS-C1-V2 drive unit
(4-1) When using serial output linear scale
(4-2) When using analog output linear scale
Some control restrictions may apply when using speed and current command synchronous control,
depending on the servo drive unit's control mode and control system configuration. Refer to the
following table for details.

POINT
1. Incremental control is only supported when using 2-axis servo drive unit. If
two 1-axis units are used, be sure to carry out absolute position control.
2. When synchronous control operation is carried out at 2-axis servo drive unit,
the L-axis is the master axis, and the M-axis is the slave axis.
