Function and interface
External encoder power supply: 5.2 VDC ± 5%, 250
mA max.
If the above capacity is exceeded, provide a
separate power supply.
This is an external encoder serial bi-directional
signal.*(Conforming to EIA485)
Maximum response frequency: 400 Mpps
This is an external encoder 90° phase input signal.*
Maximum response frequency: 4 Mpps (quadruple
multiplier)
