Signal termination
Incremental RS422A,
Push-Pull
3-phase operation, 4+2 and 8 lead cable, winding for 1 voltage, delta or
star connection (internally connected)
The termination with resistor and capacitor (RC) can reduce noise.
Hint
The signal sequence of A and B depends on the gear ratio of the drum motor.
Therefore the rotation direction can be different for drum motors with the same
number of poles and power but different speed. In this case the signal cables A
and B can be interchanged.
