  • Page 23: Technology

    The EL7031 and EL7041 Stepper Motor terminals differ in terms of performance. EL7031 With a size of only 12 mm, the EL7031 [} 16] covers the lower performance range. The supply voltage can be up to 24 V . The device is designed for simple integration into the 24 V control voltage system.
  • Page 24 EtherCAT Terminal. The EL7031 and EL7041 apply a controlled current to the motor winding. If the supply voltage falls below the nominal voltage, the power output stage can no longer apply the full current, resulting in a loss of torque. It is desirable to aim for systems with small winding resistance and high supply voltage in order to limit warming and achieve high torque at high speeds.
  • Page 25 (transmission). An elegant solution for improving positioning accuracy is the microstepping function offered by the EL7031 and EL7041. It enables up to 64 intermediate steps. The smaller "artificial" step angle has a further positive effect: The drive can be operated at higher speed, yet with the same precision. The maximum speed is unchanged, despite the fact that the drive operates at the limit of mechanical resolution.
  • Page 26 Product overview 8. Different measures are available for optimizing the performance of the drive: using lighter materials or hollow instead of solid body, reducing mechanical mass. The control system can also have significant influence on the behavior of the drive. The Bus Terminal enables operation with different supply volt- ages.

  • Page 30: Ethercat State Machine

    Basics communication Example "Set SM watchdog" This checkbox enables manual setting of the watchdog times. If the outputs are set and the EtherCAT communication is interrupted, the SM watchdog is triggered after the set time and the outputs are erased. This setting can be used for adapting a terminal to a slower EtherCAT master or long cycle times.

The EtherCAT master initializes sync manager channels 0 and 1 for mailbox communication. Pre-Operational (Pre-Op) During the transition between Init and Pre-Op the EtherCAT slave checks whether the mailbox was initialized correctly.

    Appendix Fig. 200: Configuration is identical otherwise a change dialog appears for entering the actual data in the configuration. Fig. 201: Change dialog In this example in Fig. "Change dialog", an EL3201-0000-0017 was found, while an EL3201-0000-0016 was configured. In this case the configuration can be adapted with the Copy Before button. The Extended Information checkbox must be set in order to display the revision.
