CMPx.ADVANCE

Description

Use this keyword to compensate for slow output devices such as relays or mechanical devices. The value of this parameter determines how long in advance the compare engine will trigger to compensate for a slow output.

For example, if CMP0.ADVANCE = 10, and CMPx.SETPOINT = 1,000,000 counts while the source is moving at 100,000 counts/sec (positive direction), then the compare will trigger when the source value crosses 999,000 counts. This will be 1000 counts early, or 0.01 seconds of 100,000 counts/sec.

CMPx.ADVANCE has a 0.001 ms resolution.
