For coordinating all IP 266 tasks
For servicing the IP 266 via the COM 266 software
• Start-up
• Input/modification of machine data
• Test mode: Starting traversing programs
Starting single modes/jobs
For servicing the IP 266 via a STEP 5 program
• Starting traversing programs
• Starting single modes (jobs)
• Reading single values from the IP 266 (actual
value, distance to go, following error)
• Acquiring and evaluating status info
Input for an incremental position encoder. The
counter counts the encoder pulses.
Digital-analog converter: Analog output to the
motor power section. The DAC converts the digi-
tal setpoint into an analog setpoint.
