Drawing
RDDS1-160xH dimensional drawing. Shows outer contour, measuring system connecting cable, motor connecting cable positions and Index position (commutation reference). Height H varies by model (120 / 145 / 170 / 195 mm); stage plate inner diameter dsp = 50 H6, base plate inner diameter dbp = 60 H7.
System Data
Notes
Tolerance range for values: ±5%. On housing of rotary system the maximum temperature of 60 °C must not be exceeded by default.
* In few cases the limiting speed is limited by the winding version of the motor.
