Overview
|
|
EM2RS series stepper drives are based on standard Modbus RTU protocol, using RS485 communication can network up to 31 axes.
Their built-in PR feature with 16-segment position table (PR Mode) can save additional controllers in most of point-to-point applications, to greatly enhance system reliability and reduce the cost.
|
Applications
|
EM2RS series also support the feature of teaching, the operation modes of Profile Position, Profile Velocity and Homing. They can power 2-phase NEMA 8, 11, 14, 17, 23, 24, 34 stepper motors.
