Pulse Outputs Section 5-2
Remarks
1,2,3...
1. PLS22(887) used a relative pulse setting. This enables operation even if
the origin is not defined. The present position in A276 (lower 4 digits) and
A277 (upper 4 digits) is set to 0 before pulse output and then contains the
specified number of pulses.
2. ACC(888) can be used instead of SPED(885) for the jog operation. If
ACC(888) is used, acceleration/deceleration can be included in the jog op-
eration.
