CAUTION
When orientation control, encoder feedback control, and vector control are used, an encoder is shared.
Use the encoder with a number of pulses of 1000 to 4096P/R.
Couple the encoder with the motor shaft or with the shaft that stops the main shaft at the specified position.
Couple it with the speed ratio of 1:1 and without any mechanical looseness.
To ensure correct operation, the encoder must be set in the proper rotation direction and the A and B
phases connected correctly.
