5.19.2 PCD2.H32x, motion control modules for servo-drives
There are four module types available:
PCD2.H320: 2 axes with 24 V encoder
PCD2.H325: 2 axes with 5 V and SSI absolute value encoder
PCD2.H322: 1 axis (slave operation) with 24 V encoder
PCD2.H327: 1 axis (slave operation) with 5 V and SSI absolute value encoder
The PCD2.H32x motion control modules are intelligent I/O modules in the PCD2
series. They are used to position two independent axes, with one variable speed
AC or DC drive (servo-motor) each, or two axes as an electronic transmission.
This requires the drive unit to have a power stage and incremental shaft encoder
for capturing position or speed. Displacement control may also be achieved with
an SSI absolute value encoder.
Each module contains a DSP processor that independently controls every
movement according to parameters supplied by the user program: velocity,
acceleration and destination position (“PID control”). This enables each axis
to execute independent movements, perform S-curve and trapezoidal motion

the current axis position during motion.
In a PCD2 with expansion housing, up to 7 PCD2.H32x modules can be operated
in parallel.
