Controllers & Drivers - AC Servo Motor Drivers

  • LECS, AC Servo Motor Driver, Pulse Input Type

    These LECS drivers for AC servo motors use pulse input for standalone operation by a PLC.  The LECSA drives motors with 17-bit incremental encoders, while the LECSB drives motors with 18-bit absolute encoders.  The LECSB-T drives motors with a 22-bit absolute encoder.  LECSB-T is also compatible with an additional larger motor, adds the STO safety function, and includes push operation capability.  LECSA and LECSB-T also include positioning tables as an alternative to pulse input.

  • LECSN-T, AC Servo Motor Driver, Ethernet Protocols

    The LECSN-T driver combines a common chassis for power and actuator connections with a slot for interchangeable network cards.  Cards are available for EtherNet/IP™, EtherCAT®; and PROFINET.  Each card includes two 100BASE-TX Ethernet ports for multiple wiring configuration.  Each driver can be configured to include the desired network card, but separate cards are also available for changing installation requirements.  LECSN-T drives an AC Servo motor with a 22-bit absolute encoder.  Real time tuning and vibration suppression control adapt to current conditions as equipment wears over time, leading to short settling times and reduced downtime.  Synchronous motions is possible with the EtherCAT® version.

  • LECSC, AC Servo Motor Driver, CC-Link

    The LECSC drivers are compatible with the CC-Link v1.10 open industrial network, operating AC servo motors with 18-bit absolute encoders.  Direct input can be given over the network, at up to a 10 Mbps transmission speed.  A positioning table with 255 data points is also available.

  • LECSS, AC Servo Motor Driver, SSCNET Protocols

    The LECSS drivers are compatible with the Mitsubishi's servo system controller network, or SSCNET.  LECSS-S drives an AC servo motor with an 18-bit absolute encoder and is compatible with SSCNETIII at up to 50 Mbps bidirectional transmission speed.  LECSS-T drives an AC servo motor with a 22-bit absolute encoder, and is compatible with SSCENTIII/H, offering an even higher 150 Mbps bidirectional transmission speed.  LECSS-T also adds the STO safety function, improved noise reduction and C-UL-US listing.  Both driver types offer pushing operations and are capable of sychronous motion in multi-axis applications.

  • LECY, AC Servo Motor Driver, MECHATROLINK Protocols

    The LECY drivers are compatible with the MECHATROLINK open field network, operating AC servo motors with 20-bit absolute encoders.  LECYM uses the MECHATROLINK-II protocol to connect up to 30 units at a max distance of 50m with 10 Mbps transmission speed.  LECYU uses the MECHATROLINK-III protocol, connecting up to 62 units at a max distance of 75m between units, with 100 Mbps transmission speed.  Synchronous motion control is possible with additional equipment.
