Technical data of the encoder

Stepper motors are designed for positioning tasks. Beckhoff stepper motors have a step angle of 1.8° (which is 200 steps/rotation). Stepper motor terminals enable each individual step to be approached. This enables positioning without feedback / encoder. The micro-stepping mode of the stepper motor terminal can be used to improve the physical resolution further. This causes the physical resolution to be multiplied by the micro-step factor. The stepping pattern can be adjusted from full steps, through half steps down to 64 micro-steps.
It is possible that, when overloaded, a stepper motor cannot keep up with the desired number of steps. This is referred to as the stepper motor "losing steps". It is therefore possible, optionally, to add an incremental encoder. This requires a second shaft end at the stepper motor.
For stepper motors with incremental encoder, the stepper motor output stage KL2541 / EL7041 / EL7037 or EP7041-3002 must be used.
