● Optical ruler ABZ signal phase sequence
Suppose the encoder’s rotation direction is opposite to the figure above. In that case, if the wiring is
not to be adjusted, the phase sequence of A phase and B phase can be changed by modifying the
Cn097.2 parameter.
Cn097.2 Pulse encoder signal input phase sequence
Initial Value Unit Setting Range Effective RS-485 Address
0 -- 0 ~ 1 Power reset 0064H
Setting description:
Setting Description
0 Pulse input A phase is ahead of B phase
1 Pulse input A phase is behind B phase
If the optical ruler does not have the Z phase signal or the user does not need to use the Z phase signal
as the reference point for returning to the origin, the do not detect pulse encoder Z phase
disconnection function can be set as enabled so that the driver can still drive even without connecting
the Z phase signal of the encoder.
Positive direction of the motor
Time
A phase surpasses B phase
