  • Page 11: System Structure

    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. an axis from Festo. 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.

    Detailed information about the required mounting clearances and any power reduction that may be necessary as a function of the ambient temperature è Fig.16 Festo — CMMT-ST-C8-1C-...-S0 — 2019-01...
  • Page 18 The necessary clearances are determined by the temperature in the control cabinet and the required effective current. The PositioningDrives software from Festo can help to calculate the effective current. If the clearances are set too low, the device will be switched off by the I²t or temperature monitoring function of the output stage.
