Electrical Specifications

Voltage

Nominal voltage ... 24 VDC

Maximum voltage ... 32 VDC

Minimum voltage ... 18 VDC

Frequency

Nominal frequency ... 500 Hz

Maximum frequency ... 600 Hz

Minimum frequency ... 400 Hz

Duty Cycle

Duty cycle at full counterclockwise rotation ... 1%

Duty cycle at full clockwise rotation ... 100%

Note: The position sensor should be viewed from the shaft end.
