Hey guys
I'm building a program that has position control with hydraulics. I have three valves: left, right and creep.
I'm using variables: setpoint, actual value, limit low, limit high, deadband, creepband (don't know how else it's written.)
I have two movement speeds: normal and creep.
Setpoint is changed manually by operator.
Machine is cutting wood. Cutting tolerance is bigger than deadband, usually.
In one PLC program i saw, that initially program does not consider deadband. Only after actual position has overshoot setpoint and movement reverses is deadband considered.
Is that correct? I based my program on that. I haven't done any programs for this situation so i lack know-how.
