I/O Type: Single Ended 5v Inputs / Outputs
Circuit Type: Sink (4.7K ohm pull-up to internal +5v)
Input Impedance: 4.7K ohms to internal +5v
Maximum Input Voltage: -1.0 v, +7.0v
Logic 0 Input Threshold: +0.8 v max
Logic 1 Input Threshold: +2.4 v min
Input Filtering: 10 microseconds typical
Output Sink Current 10 mA max
On State Output Voltage +0.5v at 10 mA
Strobe Response: Minimum Pulse Width: 10 microseconds. Position
Capture Accuracy: +/- 2 counts with an additional 10
microseconds of variance
Note: For digital servos, these points act as the PWM / ENBL outputs and Alarm inputs. For Analog Servos
and Aux axes, these points are input only. The listed 0v pins should be normally used for the signal
return.
