Encoders
(“ENCODERS” and “MASTER ENCODER” connectors)
ENCODER INPUTS: Differential comparator accepts two-phase quadrature incremental encoders with
differential (recommended) or single-ended outputs. Max. frequency is 12.0 MHz post quadrature.
TTL-compatible voltage levels: Low
≤
0.4V, High
≥
2.4V. Maximum input voltage is 5 VDC.
MASTER ENCODER: The master encoder is used for Following, and not for servo feedback or stepper
stall detect. The pin outs are the same as the other encoders, except that pin 8 is ISO GND (can’t use a
single-ended encoder).
NOTE
:
When connecting a –HJ single-ended
encoder to the 6K, be sure to
connect the encoder’s white lead
(channel A+) to pin #2 (A+). The
current Installation Guide incorrectly
shows the white lead connected to
