Controllers & Drivers – 24VDC Step Motor ControllerThe 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.
The LECP6 is a controller for LE’s 24VDC step motors. Enter up to 64 motion control step data with position, speed, acceleration, and pushing force so they can be called in any sequence by the PLC. Data entry requires laptop software or a teaching pendant. An Easy mode for data entry is available for quick start ups, as well as the more detailed Normal mode. Additional features include separate control and motor power, alarm detection, and in-range AREA output signals.
The LECP7-XB3 is a controller for LE's 24VDC step motors. It is similar to the LECP6 controller, with the addition of a battery backup. The motor position signal can be monitored immediately after power is shut off or lost, regardless of the actuators operation. A return to origin is not required after power recovery. The nickel hydride battery has a 72 hour recharging time, up to 20 days of position retention, and a 2-yr replacement life.
The LECP1 is a programless controller for LE’s 24VDC step motors. 14 positions with speed and acceleration / deceleration values can be set directly from the control panel. No setting software or teaching pendant is required. Separate control and motor power enable the motor to be turned off without losing the encoder position. Alarm detection is also available.
The LECP2 is a programless controller exclusively available for the LEM series. 12 intermediate positions along with the 2 stroke end points can be set directly from the control panel. When LEM stroke adjust units are used, the controller’s stroke study registers end positions with one button. A reduced wiring option allows fewer inputs if 3 or less positions are required. This model excludes the pushing operation available on the LECP1.
The LECPA is a driver for LE’s 24VDC step motors. This driver controls motion by interpreting a pulse input signal from the PLC instead of calls to a step data table. Separate control and motor power enable the motor to be turned off without losing the encoder position. Additional features include alarm detection and in-range AREA output signals.
The LECPMJ is a controller for LE’s 24VDC step motors, compatible with CC-Link v1.10 fieldbus. Fieldbus compatibility permits position and speed monitoring by the PLC, as well as step data entry. Up to 42 controllers can be connected, depending on the parameter definition mode desired at the PLC. Up to 64 motion control step data can also be set by laptop software or a teaching pendant.
The JXC73, 83 and 93 are 4-axis controllers for LE's 24VDC step motor driven electric actuators. Four electric actuators can be controlled within one package, simplifying wiring and economizing space. Further, the coordination of complex movements is possible. These movements include 2-axis arc or circular interpolation, 3-axis linear interpolation, and 4-axis speed matching. The speed matching feature corrects for speed differences between axes that could result from external forces or other factors. Synchronous positioning with feedback between axes is not available. JXC73 and JXC83 are NPN and PNP parallel I/O types using two 40-pin cables. JXC93 uses the EtherNet/IP™ fieldbus protocol to communicate with the PLC. One line of step data can be called for up to 4 axes of force and movement instructions. Typical applications include pick and place gantry movement, multi-axis lifting while maintaining orientation and stability, and non-linear path tracing for graphics production or dispensing.
The JXC92 is a 3-axis controller for LE's 24VDC step motors, compatible with EtherNet/IP™ fieldbus. Three electric actuators can be controlled within one package, simplifying wiring and economizing space. Further, the coordination of complex movements has been added. These movements include 2-axis arc or circular interpolation, and 3-axis linear interpolation, along with speed tuning control. A call to one line of step data can include force and movement instructions for up to three axes. Typical applications include pick and place sorting or filling, lifting, and non-linear path tracing for graphics production or dispensing.
The JXC*1 is a single axis controller for LE's 24VDC step motors compatible with several fieldbus protocols including Ethernet/IP™ fieldbus. Actuator motors can be operated by calling a line of step data or by direct numerical instruction, each possible over the network. Futher fieldbus compatible functions include return to origin, alarm outputs and resets, parameter setup, status monitoring, and trial runs.
