A-4-2 Pulse Output Start Time; A-4-3 Response Times Of Pulse Output Changes - Omron SYSMAC CJ Series User Manual

A-4-2 Pulse Output Start Time
The pulse output start time is the time required from executing a pulse output instruction until pulses are
output externally. This time depends on the pulse output instruction that is used and operation that is
performed.
Instruction execution
Pulse output
Pulse output instruction
SPED(885), continuous
SPED(885), independent
ACC(888), continuous
ACC(888), independent, trapezoidal
ACC(888), independent, triangular
PLS2(887), trapezoidal
PLS2(887), triangular
IFEED(892)
A-4-3 Response Times of Pulse Output Changes
The pulse output change response time is the time for any change made by executing an instruction
during pulse output to actually affect the pulse output operation.
Pulse output instruction
INI(880,) immediate stop
SPED(885), immediate stop
ACC(888), deceleration stop
PLS2(887), deceleration stop
SPED(885), speed change
ACC(888), speed change
PLS2(887), target position change in reverse
direction
PLS2(887), target position change in same
direction at same speed
PLS2(887), target position change in same
direction at different speed
Note: The pulse control cycle is set in the PLC Setup to either 1 ms or 4 ms.
