Electric Actuators – Controllers & Drivers

24VDC Step Motor Controller

24VDC Step Motor Controller

The 24VDC step motor, LE’s most common motor, includes encoder feedback. It is ideal for transfer of a high workload at a low speed, and for pushing operations. SMC offers numerous controllers to operate these step motors, depending upon the desired relationship with the PLC. Step motors can be controlled by calls to a step data table, by pulse input from the PLC, or over a fieldbus network. A programless controller is also available.


24VDC Servo Motor Controller

Several series, including rod, slider and slide table types, can be configured with a 24VDC servo motor. Maximum work load is lower than the step motor, but remains constant over the full speed range. Servo motors can be operated by a step data table controller interfacing directly with the PLC, or via fieldbus network directed by a gateway unit.


24VDC Fieldbus

24VDC Fieldbus

SMC offers several fieldbus protocol enabled controllers for LE’s 24VDC step motor actuators. Single axis direct input controllers are available for Ethernet/IP and CC-Link. Also, there is a 4-axis controller with Ethernet/IP capability. A gateway device offers network access using CC-Link DeviceNet, Profibus or Ethernet/IP protocol as well. The gateway can connect up to 12 RS485 serial controllers, including both the LECP6 for step motors and the LECA6 servo motors.


AC Servo Drivers

AC Servo Drivers

LE’s AC servo motors offer higher speeds and accelerations than DC types, as well as higher torques for larger actuators. Incremental and absolute pulse input drivers are available, as well as network models for CC-Link fieldbus protocol and Mitsubishi’s SSCNET.


Card Motor Controller

The LATC4 controller exclusively operates the LAT3 magnetic drive card motor. Laptop software is easy to follow, including screens for step data and I/O setup, as well as monitoring and testing operations. The easier of two step data entry modes requires only target position, positioning time, and load weight.
