Availability of synchronous mode in control mode

Availability of synchronous mode (DC mode) and asynchronous mode (Free-run mode) in each mode is shown in the
following table.
Control mode
Cyclic synchronous position mode
Cyclic synchronous position mode (csp)
Cyclic synchronous velocity mode
Cyclic synchronous velocity mode (csv)
Cyclic synchronous torque mode
Cyclic synchronous torque mode (cst)
Homing mode
Homing mode (hm)
*1 If a servo motor is driven with this combination, [AL. 09E.9 Control mode setting warning] will occur.
6.2

Synchronous mode (DC mode)

In the synchronous mode, the synchronous jitter needs to be kept less than 2 μs. If the synchronous jitter is 2 μs or more, an
error may be detected and an alarm may occur.
