Specifications

The specifications below apply to only the MID-76xx. Please refer to your controller specifications	General (All MID 76xx drives)
to determine overall system specifications.	Encoder Interface (Each Axis)
Some signals define compatibility as pass-through. This means the MID 76xx may have passive filtering	Inputs	Quadrature, incremental
	Differential input threshold	±0.3 V (typical)
on these signals, but the signals do not affect the voltage range. Consult your motion controller
	Single-ended input threshold	TTL/CMOS
specifications to determine allowable voltage range and logic level compatibility of the signal.
	Voltage range	0 to 5 VDC
	Maximum quadrature frequency	20 MHz
