Electric Actuators – Controllers & Drivers
Controllers and drivers needed for our electric actuator family. You will find step motor, servo motor and card motor controllers as well as 24VDC Fieldbus gateway units and AC servo drivers.
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.
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.
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.
The JXCL1 is a single axis controller for the 24VDC step motors of LE series electric actuators. This controller supports the IO-Link communication protocol. When paired with an IO-Link master, it is possible to monitor status, reset alarms, set step data, and input motion controls directly from the PLC's HMI screen. A full range of parameter settings are available. IO-Link enables settings recovery when changing the controller for any reason. JXCL1 incorporates IO-Link version 1.1 and com3 speed.
- 14 input bytes (controller to master) for operation monitoring via IO-Link
- 22 output bytes (master to controller) for direct operation via IO-Link
- 64 lines of step data available to set by master, laptop or pendant
- Software configuration via laptop or teaching pendant (sold separaely)
- Screw bracket or DIN rail mounting
- 3 LED status indicators
LE’s AC servo motors offer higher speeds and accelerations than DC types, as well as higher torques for larger actuators. Pulse input drivers are available for both incremental and absolute encoders, for standalone operation by a PLC. Drivers for fieldbus networks are also available, including compatibility with EtherNet/IP™, PROFINET, EtherCAT®, CC-Link, Mitsubishi's SSCNET and Yaskawa's MECHATROLINK protocols.
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.
