6.17.4 PCD3.H210, Motion control module for stepper motors
Application
The PCD3.H210 module provides fully autonomous control and monitoring of
stepper motor travel, with run-up and braking ramps. The commands for stepper
motor motion cycles are transmitted to the module by function blocks in the user
program.
Duringmotion,theSMprocessormonitorsthefrequencyproleandtheaccelera-
tion and braking ramps to move the axis to the destination position without loss of
steps. Each module controls an independent axis. The module supplies a mono-
phase pulse string which is conveyed to a suitable electronic drive. The module
has 4 inputs and 4 outputs.
This I/O module cannot currently be used with the PCD3 RIO head station
