KH series stepper motors
28/42/57/86mm
48/51/56/58/60/65/76/80/84/118/156/165/201mm
D = single shaft
SZ = double shaft
Blank = without brake
B = with brake
Blank = without feedback
**IE = Incremental encoder
*** AE = Absolute encoder(RS485, Modbus RTU)
Blank = Without integrated mounted stepper drive
DRC = stepper driver mounted on the side of the motor
DRH = stepper driver mounted at the rear end of the motor
*It is not possible to install both brake and position feedback devices on one single motor.
**In order for the incremental encoder signal to be received and processed by the closed-loop stepper drive, the encoder output signals must be 5V differential signals with a maximum resolution of 2500PPR.
*** The absolute encoder feedback signals need to be received and processed by the user′s controller.
