motor position
#1
I am running a stepper motor using an ACC-24E2S in open loop on MACRO ring. The motor has an encoder on it and I want to know if I can monitor the position of the motor using the encoder without actually closing the loop?

i.e. MSx,MI910=8 and still access the encoder value. Is it still stored in the ECT and how can I access it?

Cheers,
Mark

You can monitor the position, but it will have to be through another hardware channel, if available. The same IC hardware is used for real encoder or open loop stepper. You can continuously monitor position in a PLC and kill a move if there is excess error, or you can do a pull-in move at the end of the move, or both.
