AC Servo Drivers

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.

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…
LECY, AC Servo Motor Driver, MECHATROLINK Protocols
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…
LECSN-T, AC Servo Motor Driver, Ethernet Protocols
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™, EtherCATreg; 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…
LECSC, AC Servo Motor Driver, CC-Link
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.  The LECSC-S driver can operate in 2 voltage ranges,…
LECSS, AC Servo Motor Driver, SSCNET Protocols
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…
