10. Description of ROD 450 Rotary Encoder
The ROD 450 serves to test counting function and interpolation of ND, VRZ, IBV EXE etc.
Moreover, it is suited to preset the oscilloscope trigger for checking the reference mark with PWM 8.
10.1 Specifications of ROD 450

11. Description of Connecting Cable 10-30V DC
The connecting cable serves to power the PWM externally with 24V dc (e.g. control voltage of
the machine tool).
Note: The potential of the control voltage must be separated from the encoder voltage.
measuring circuit error may occur without potential segregation.
