Parameters
PM.005
Default: 11
8
Format: DEC
Settings:
This parameter improves the motor resolution with interpolation magnification. It is applicable to sine
wave encoders and not applicable to pulse encoders.
The resolution of the sine wave encoder after interpolation is PM.004 x 2
PM.006▲●
Default: 0x0000
Format: HEX
Settings:
During the motor parameter identification process, the servo drive automatically detects the phase
sequences of the motor UVW and Hall sensor. You can use this parameter to obtain this information.

X: motor UVW phase sequence and encoder incremental direction
0: when A phase is ahead of B phase, the motor phase sequence is U, V, and W.
1: when A phase is ahead of B phase, the motor phase sequence is U, W, and V.
