  1. One of my customer need to replace old clutch controller. I try to use V130-33-TR20. START and BRAKE clutch + motor hardware with encoder (300 ppr) and home sensor present in my lab. Then i try to program ladder for stop rotating shaft in zero position. O0 (RUN) relay output - for START, O2(STOP) relay output - for BRAKE. Result: 1. When only START clutch (RUN output) is used - overshoot is 110-120 pulse (1200 pulse per one shaft rotation present). 2. When use START clutch and BRAKE clutch (RUN and STOP output) - overshoot is 17-20 pulse. 3. When use START clutch and BRAKE clutch, 2.5ms interrupt and immediate input and output -overshoot is 10-12 pulse. 4. When use START clutch and BRAKE clutch, 1.25ms interrupt and immediate input and output -overshoot is 7-10 pulse. Relay outputs for clutch control do not have sufficient durability. Then i use two solid state relay and try to use npn outputs O6 and O7 for control START and BRAKE. And result So the question is: how to recognize which of the PLC transistor outputs support the immediate output? As i see HS output in V130-33-TR20 is not immediate output, however, is this the rule for all Vision PLCs integrated output and SNAP-IN output? Yes i can write program for different PLC and compile for test ... but maybe some document present with transistor output possible modes.
