6.18.2 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.H322:1axis(slaveoperation)with24Vencoder
PCD2.H327:1axis(slaveoperation)with5VandSSIabsolutevalueencoder
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
orDCdrive(servo-motor)each,ortwoaxesasanelectronictransmission.
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
destinationposition("PIDcontrol").Thisenableseachaxistoexecuteindependent
movements,performS-curveandtrapezoidalmotionproles,changevelocityand
acceleration, perform interrupt functions and record the current axis position during
motion.
In a PCD2 with expansion housing, up to 7 PCD2.H32x modules can be operated in
parallel.
