Table 6.22: J2- Motor Encoder Connector Pin-Outs
Motor Encoder Pin Number Description
EPWR J2-1
J2-3 Encoder power
Internally fused (F3) is 1A, fast acting.
ECOM J2-2
J2-4 Encoder common
SENSE (+)
SENSE (-) J2-5 (+)
J2-6 (-) Encoder power sense
NOTE: The SENSE+ signal must be connected to the EPWR sig-
nal, and the SENSE- signal must be connected to the ECOM sig-
nal at the encoder for the motor encoder signals to be received
properly by the drive.
A(+)
A (-) J2-7 (+)
J2-8 (-) Motor Encoder Input Channel A(+) and Channel A(-). Accepts TTL
level signals from a line driver.
B(+)
B (-) J2-9 (+)
J2-10 (-) Motor Encoder Input Channel B(+) and Channel B(-). Accepts TTL
level signals from a line driver.
I (+)
I (-) J2-11 (+)
J2-12 (-) Motor Encoder Input Channel I(+) and Channel I(-). Accepts TTL
level signals from a line driver. Output pulse occurs once per motor
shaft revolution.
