Servomotor with integrated controller CM1-x-17L30E

AC24 Vhigh-speed

Overview

• CM3+: Standard model. Servo motor which enables to build a system.
• CM3M: Modbus RTU (RS485) compatible model. A PLC or PC can be used as a master, and up to 32 axes can be connected as slaves.
• CM3: Low-cost innovative model with improved torque and high-speed performance from CM1 to achieve servo-equivalent performance with a stepping motor.
• CM2: High-end model. Extensive functions such as PLC function, daisy-chain, interpolation function, etc.
• CM1: Legacy model. Long seller with better resolution, quietness, and functionality compared to CM3.
