NOTE
• The encoder can be shared under orientation control, encoder feedback control or vector control. Use an encoder which has
a pulse count of 1000 to 4096 ppr (pulse per revolution).
• 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 must be
connected correctly.
