phase loss
1: The cable between drive and motor is faulty.
2: The drive's three-phase output is unbalanced
when the motor is running.
3: The drive board is faulty
4: The IGBT is faulty.
1: Check the cable.
2: Check the motor windings.
3 to 4: Seek for maintenance.
Err14

Seek for maintenance.
Err21
EEPROM
read-write fault
The EEPROM chip is damaged.
Seek for maintenance.
Err26
Beyond the
accumulative
running time
limit
The accumulative running time reaches the setting
value F8-17.
Clear the record through the parameter initialization
function, set FP-01=2.
