Pulse Outputs Section 5-3
5-3-4 Pulse Output Patterns
The following tables show the kinds of pulse output operations that can be
performed by combining various pulse output instructions.
Continuous Mode (Speed Control)
Starting a Pulse Output
No-origin Flags
ON when the origin has not been deter-
mined for the pulse output.
0: Origin established.
1: Origin not established.
A280.05 A281.05 A326.05 A327.05
At-origin Flags
ON when the pulse output PV matches
the origin (0).
0: Not stopped at origin.
1: Stopped at origin.
A280.06 A281.06 A326.06 A327.06
Output Stopped Error Flags
ON when an error occurred while output-
ting pulses in the origin search function.
0: No error
1: Stop error occurred.
A280.07 A281.07 A326.07 A327.07
