NOTE
• When orientation control, encoder feedback control, vector control are used together, the encoder is shared between these
controls. Use an encoder which has a pulse count of 1000 to 4096 ppr (pulse per revolution).
• The encoder should be coupled with the motor shaft or the spindle oriented with a speed ratio of 1 to 1 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.
