  • Page 10: Additional Information

    The servo drive CMMT-ST is a 1-axis servo drive for controlling a stepper motor or an EC motor with connected mechanisms, e.g. a Festo axis. The device is controlled by a higher-level controller using the bus protocol EtherCAT, EtherNet/IP or PROFINET, depending on the product version, via a real-time Ethernet interface.

    The series CMMT-ST servo drives can be connected in series. With effective output currents > 4.5 A mounting clearances may be required on both sides to allow dissipation of the heat generated during operation by allowing sufficient air flow. Festo — CMMT-ST-C8-1C-...-S0 — 2021-04b...
  • Page 17 The necessary clearances are determined by the temperature in the control cabinet and the required effective current. The Festo PositioningDrives software can be used to calculate the effective current. If the clearances are insufficient, the device will be switched off by the I²t or temperature monitoring function of the power stage.
