protection
1. 電機驅動電源電壓過高，220V 電源電壓超過限定值
（AC310V ），或負載慣性過大導至再生電壓超過限定值
(DC440V),或電壓檢測回路故障。
注：（110V 控制系統電源電壓超過限定值（AC155V），或負
載慣性過大導至再生電壓超過限定值(DC220V)。
1. The motor drive power supply voltage is too high, the 220V
power supply voltage exceeds the limit value(AC310V), or the
load inertia is too large to the regenerative voltage exceeds the
limit value(DC440V), or the voltage detection circuit fails.
Note:(110V control
system power supply voltage exceeds limit
value(AC155V), or load inertia is too large to regeneration voltage
exceeds limit value(DC220V).

1. 電機驅動電源電壓過低，220V 電源電壓低於限定值
（AC91V），或電機驅動電源電壓低於限定值（DC130V）,或
電壓檢測回路故障。
注：（110V 電源電壓低於限定值（AC45.5V），
或電機驅動電源電壓低於限定值（DC65V））
1. The motor drive power supply voltage is too low, the 220V
power supply voltage is lower than the limit value(AC91V), or the
motor drive power supply voltage is lower than the limit
value(DC130V), or the voltage detection circuit fails.
Note:(110 V power supply voltage is below the limit(AC45.5 V), or
motor drive power supply voltage is below the limit(DC 65V))
