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 profile 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
