1.2 Function and application
The ..H3.. module is used to position a single axis with variable speed
control DC or AC servomotors. This requires the drive unit to have a
power stage and incremental shaft encoder for capturing position or
speed. In a PCD1 system up to 4 motion control modules (4 axes) and in
a PCD2 up to 8 ..H3.. modules (8 axes) can be plugged anywhere on the
I/O bus and operated together with all base units.
The motion control module contains a single-chip processor that inde-
pendently directs and PID controls every movement according to pa-
rameters supplied by the user program (velocity, acceleration and desti-
nation position). This enables each axis to be controlled independently. It
is possible to program the linkage of several axes (point-to-point) in co-
ordinated, quasi-synchronous mode. Linear motion is thereby achieved
with cartesian axes.
PCD2.H31x motion control modules should be plugged into the
PCD2.M1xx base unit and not the PCD2.C1xx expansion unit. This is to
take account of the relatively high current consumption.
