5.18.1 PCD2.H210, Motion control module for stepper motors
Application
The PCD2.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 acceleration
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 monophase pulse
string which is conveyed to a suitable electronic drive. The module has 4 inputs and 4
outputs.
