Fig. 12.1.7 Timing chart
Input start commands simultaneously with the DI signal or serial communication from controllers
such as programmable controllers. The start delay time of the main shaft and driven shaft is 888 µs
at a maximum because it depends on the fetch cycle of the start signal. The detection of external
input signals is delayed by the time set in the input filter setting of [Pr. PD29].
Even though CAMC turns on, the command is not reflected after ST1 turns on (during point table
operation or JOG operation). The command is not also reflected even though CAMC turns on in the
servo-off state.
CAMC is determined at the on edge, not on level. Even though CAMC turns off or on before CAMS
turns on, the command is not reflected.
