Description of Alarm/Error |
| 1 |
HV (Overvoltage Alarm) |
If DC voltage of main circuit power supply is abnormally high, over voltage alarm occurs. |
| 2 |
LV5V (Control power supply undervoltage) |
Alarm occurs if control circuit power supply voltage (+5V) is abnormally low. |
| 3 |
LVDC (DC Link undervoltage alarm) |
Alarm occurs if DC voltage of main circuit power supply is abnormally low. |
| 4 |
DCSW
(Regenerative control circuit abnormality) |
Alarm occurs when short time regeneration discharge energy is too high. |
| 5 |
DCOH (Excessive regenerative discharge alarm) |
Alarm occurs when average regenerative discharge energy is too high. |
| 6 |
OH (Servo amplifier overheat) |
Alarm occurs when thermostat in amplifier operate. |
| 7 |
MCC (Magnetic contractor welding alarm) |
Alarm occurs when magnetic contactor contact welds. |
| 8 |
HCL (Overcurrent alarm) |
Alarm occurs when abnormally high current flows in main circuit of 1-axis amplifier or in main circuit of L axis of 2-axis amplifier. |
| 9 |
HCM (Overcurrent alarm) |
Alarm occurs when abnormally high current flows in main circuity of M axis of 2-axis amplifier. |
| b |
HCLM (Overcurrent alarm) |
Alarm occurs when abnormally high current flows in main cirucits of L and M axes of 2 axis amplifier. |
