To use the Xinje VH6-DM200 encoder expansion module to set the motor rotation to a specific number of encoder pulses, follow these steps:

1. Install the ABZ incremental encoder and connect it to the CN1 input on the VH6-DM200 module using the correct pin assignments (e.g., A+, B+, Z+).

2. Set parameter P1-25 to 0 to enable the use of the ABZ incremental encoder.

3. Set parameter P1-26 to the correct pulse per rotation (PPR) value of your encoder. Valid range: 1–65535. This defines how many pulses correspond to one full motor rotation.

4. Set parameter P1-27 if needed to adjust the encoder installation angle. Valid range: 0.0–359.9°.

5. Set parameter P1-28 to define the encoder phase order (0 for forward direction, 1 for reverse).

These settings allow the inverter to accurately detect motor rotation in terms of encoder pulses and control the motor accordingly.
