| 摘要 |
The invention protects an apparatus against damage due to abnormal power supply voltage under use without stopping a motor in a motor controller of an electric reel being connected with an external power supply. A reel control section makes a decision whether a power supply voltage detected by a power supply voltage sensor when a motor is not rotating exceeds a voltage Vh2 or not, notifies overshoot of the power supply voltage if it exceeds a first voltage, and forbids driving of the motor until the power supply voltage lowers down to the first voltage after overshoot is displayed at a depth of water display section.
