Description of Anomaly
Troubleshooting
Over current occurs in
acceleration; output current
exceeds by three times the rated
current of the frequency inverter
Check if the insulation of the wire from U-V-W
to the hybrid servo motor is bad
Check if the hybrid servo motor is stalled
Replace with the Hybrid Servo Controller with
larger output capacity
Over current occurs in
deceleration; output current
exceeds by three times the rated
current of the frequency inverter
Check if the insulation of the wire from U-V-W
to the hybrid servo motor is bad
Check if the hybrid servo motor is stalled
Replace with the Hybrid Servo Controller with
larger output capacity
Over current occurs when running;
output current exceeds by three
times the rated current of the
frequency inverter
Check if the insulation of the wire from U-V-W
to the hybrid servo motor is bad
Check if the hybrid servo motor is stalled
Replace with the Hybrid Servo Controller with
larger output capacity
Over current occurs when the
system is off. Unusual hardware
circuit by current detection
Send back to manufacturer for repair
Shorting of top and bottom bridges
in IGBT module are detected by
Hybrid Servo Controller
Send back to manufacturer for repair
Over voltage occurs on the
internal DC high voltage side
detected by Hybrid Servo
Controller in acceleration
Over voltage occurs on the
internal DC high voltage side
detected by Hybrid Servo
Controller in deceleration
Over voltage occurs on the
internal DC high voltage side
detected by Hybrid Servo
Controller when running
230: DC 450V
460V: DC 900V
Check if the input voltage is within the range
of voltage rating of Hybrid Servo Controller
and monitor for any occurrence of surge
voltage
For Hybrid Servo Controller with power below
22kW, the issue can be resolved by adjusting
the software brake action level in Pr.02-00
For Hybrid Servo Controller with power
above 22kW, the issue can be resolved by
adjusting the action level in the brake unit

Over voltage occurs when the
system is off. Unusual hardware
circuit by current detection
Check if the input voltage is within the range
of voltage rating of Hybrid Servo Controller
and monitor for any occurrence of surge
voltage
The DC voltage of Hybrid Servo
Controller is lower than the setting
in Pr.02-07 in acceleration
The DC voltage of Hybrid Servo
Controller is lower than the setting
in Pr.02-07 in deceleration
The DC voltage of Hybrid Servo
Controller is lower than the setting
in Pr.02-07 when running at
constant speed
The DC voltage of Hybrid Servo
Controller is lower than the setting
in Pr.02-07 when off
Check if the voltage of input power is normal
Check if there is any sudden heavy load
Adjust the low voltage level in Pr.02-07
Phase los protection
Check if only single phase power is sent or
phase los occurs for three phase models
For models with 40HP and above, check if
