| Description |
| • | To efficiently control the drive motor, you need to know the absolute location of a motor rotor (permanent magnet). |
| • | Resolver detects the absolute location of the motor rotor. |

Removal • MCU is integrated with HPCU. Therefore, to install / remove the MCU, follow the procedure for installing / removing the HPCU.
