6.3.1 Start and stop signals
(1) Make up a sequence so that the start signal is switched on after the main circuit has been established.
The start signal is invalid if it is switched on before the main circuit is established.
Normally, it is interlocked with the ready signal (RD).
(2) A start in the servo amplifier is made when the external start signal changes from OFF to ON. The
delay time of the servo amplifier's internal processing is max. 3ms. The delay time of other signals is
max. 10ms.

(3) When a programmable controller is used, the ON time of the start/stop signal should be 5ms or longer
to prevent a malfunction.
(4) During operation, the start signal (ST1, ST2) is not accepted. The next operation should always be
started after the rough match signal is output with the rough match output range set to 0 or after the
in-position signal is output.
