Series ETP25K Absolute Encoders with Pulse Width Modulation (PWM)
■PWM signal output
■Frequency 244 Hz (constant)
■Pulse width (duty cycle) 10% (0°) to 90% (360°)
■Supply voltage: 5 VDC +/-10%
●Function description PWM signal output ETP25K
■The ETP25K provides a constant carrier frequency with 244 Hz at the signal output, with HIGH and LOW signal levels which have a constant signal amplitude. A constant carrier frequency means a constant length of the period duration. The duty cycle and thus the pulse width changes in dependency of the rotating angle between 10% to 90% relative to the signal period.If the CW option is selected, the duty cycle increases clockwise when turning the shaft clockwise. If the CCW option is select-ed, the duty cycle decreases clockwise if the shaft is turned clockwise. Normally no signal conversion is required for further processing of the output signal, because many μControllers already have an input for PWM signals.
