Automatic Operation (Synchronous Control)
Precautions for settings
• Overshoot or undershoot may occur according to settings when sufficient
acceleration/deceleration time is not set for the start or stop of master axis while the advance
angle correction function is used, or when an input speed is rapidly accelerated or
decelerated by the direct connection or disconnection of a clutch while the master axis is
operated.
• When using the advance angle correction function, set a sufficient acceleration/deceleration
time on the master axis. When using the clutch function in combination, make the setting to
prevent the occurrence of a rapid acceleration or deceleration using the slip function.

• Depending on the setting of "advance angle correction reference speed" or "advance angle
correction reference amount", a calculated advance angle correction amount may exceed
the "cam control synchronous master axis cycle". When the advance angle correction
amount exceeds the "cam control synchronous master axis cycle", the "synchronous cam
master axis cycle" will be the upper limit as below. Set the parameter of advance angle
correction which meets an input speed.
