With the PR mode function, the profile command is generated in the servo drive, and the host controller only performs sequential control. Currently, Delta’s AC Servo Drive ASDA-A2 and ASDA-A3 Series support the PR mode function. The ASDA-A2 Series provides 63 profiles, and the ASDA-A3 provides 100 profiles, including homing mode, position command, speed command, jump command, write command, index positioning command and basic numerical operation.
