Harsh ZSH Stepper motor with integrated encoder In non disturbed operation the stepper motor runs synchronously to the pulses coming from the controller, that means the motor rotation (= rotation of the rotor) runs synchronously to the pulse frequency (= rotating stator field in the motor). In case of an extreme load at the motor (e.g. via a static load at the motor shaft or by accelerating of the motor) the step frequency of the motor will shortly differ from the pulse frequency within a certain maximum range. This results in changing the load angle (= difference between the real position of the rotor and its target position). For applications homing mode for monitoring the motor movement, we recommend to use a motor with an integrated encoder. ZSH Stepper motor with integrated encoder E Electrical Characteristics Supply voltage Current consumption Operating temperature to C Outputs The encoder series E monitors the motion of the motor. Together with a phytron controller (e.g. CC or phyotion series) the load angle of the stepper motor can be controlled and monitored. When the max. admissible load angle is exceeded (e.g. when the motor run is breaking down) the control unit will create an error signal.
