6.3 Digital Encoder Inputs (Driver Boards & DRV00P)
All digital encoder inputs are RS-422 standard compliant:
•
All digital encoder signals are not isolated, but are referenced to the electrical
ground (GND).
• Encoder signals must be differential pairs (using 26LS31 or MC3487 line driver
type circuits). Encoder inputs have a terminating impedance of 120 Ω.
•
Inputs are always routed on differential pairs. For a high level of signal integrity, we
recommend using shielded twisted pairs of wires for each differential signal.
•
Encoder power supply is +5 V @ 250 mA maximum (referenced to the electrical
ground) and is sourced directly by the driver boards. The +5 V power supply is low
noise (approximately 20 mVpp), fuse protected up to 500 mA/plug, and supplies
5.13 V without load.
