The motor is phased correctly when the zero-crossings of motor phases line
up with the transition points of the commutation sensor signals as shown in
the previous illustration.
Wiring Hudson Motors To Third-Party Drives
When wiring a Hudson to a third-party drive, start with a motor that is wired to
show positive encoder counts when spun CCW (viewed looking into the motor
shaft). If this is not the case, swap encoder signals A and B (for single-ended
encoders) or A and A~ (for differential encoders).
Important: the motor phases must align with their associated commutation
signal as follows (refer to phase diagram on previous page):
•
Phase T and Comm. T-R
•
Phase R and Comm. R-S
•
Phase S and Comm. S-T
Note:
Within the motion control industry, there is no standardized convention
for the labeling of encoder signals, motor phases or commutation (Hall)
signals.
Consult the servo drive manufacturer for questions regarding
the wiring of encoder outputs, commutation (Hall) outputs and motor
phases.
