Schematics
All OptoCon input and output circuits are electrically identical. To program the User I/O sig-
nals (OptoCon 1: PA0-5, PC0-3; OptoCon 2: PB0-5, PC4-7) as inputs or outputs, use the
switches S2 and S3 on the OptoCon and in conjunction with the MEI library function
init_boot_io(...)
on the motion controller. After using
init_boot_io(...)
to configure a port’s di-
rection, do not use
init_io(...)
to reconfigure the port’s direction.
The Dedicated I/O signals (Amp Enable, In Position, Positive Limit, Negative Limit, Home
and Fault)
cannot be reconfigured
. All of the I/O signals share a common supply, (
V_USER
/
USER_GND)
, which is fused at 1 amp. Additionally, each individual output is fused at 1 amp.
