Examples
4.5 ESR
4.5 ESR
4.5.1 Use of drive-independent reaction
Example configuration
• Axis A (spindle) is to operate as generator drive,
• in the event of an error, axis X must retract by 10 mm at maximum speed, and
• axes Y and Z must stop after a 100 ms delay to give the retraction axis time to cancel the
Parameterization
1. Enable the "Extended stop and retract" and "Static synchronous actions" options.
2. Function assignment:
3. Drive configuration:
4. Function enable (from part program or synchronized actions) by setting the system
5. Accelerate generator drive to "momentum" speed (e.g. in spindle operation:
