VJ Series
5-4
the AC side fuse is blown
Ground wire protection, applies
when Hybrid Servo Controller
detects the output is grounded and
the ground current is higher than
its rated value by over 50%. Note
that this protection is only for
Hybrid Servo Controller and not for
human.
Check the wire of hybrid servo motor is
shorted or grounded
Check if IGBT power module is damaged
Check if the output side wire has bad
insulation
Overheating of IGBT detected by
Hybrid Servo Controller,
exceeding the protection level
7.5~15HP: 90
℃
20~100HP: 100
℃
Check if environment temperature if too high
Check if there is any foreign object on the
heat sink and if the fan is running
Check if there is sufficient space for air
circulation for Hybrid Servo Controller
Over heating of heat sink detected
by Hybrid Servo Controller,
exceeding the protection level
(90
)
℃
Check if environment temperature if too high
Check if there is any foreign object on the
heat sink and if the fan is running
Check if there is sufficient space for air
circulation for Hybrid Servo Controller
Fan failure
Check if the fan is stalled
Send back to manufacturer for repair
Output current exceeds the
maximum capacity of Hybrid Servo
Controller
Check if the motor is overloaded
Increase the output capacity of Hybrid Servo
Controller
Servo motor overloaded
Change the product conditions
DC Fuse blown on (FUSE), for
models below (including) 30HP
Check if the transistor module fuse is bad
Check if the load side is shorted
Abnormal memory write in
Abnormal memory readout
Press RESET key to return all parameters to
factory default values
If the above does not work, send back to
manufacturer for repair
Detection of abnormal output of
three-phase total current
Detection of abnormal current in U
phase
Detection of abnormal current in V
phase
Detection of abnormal current in W
phase
Turn off the power and restart. If the same
problem persists, send back to manufacturer
for repair
When external EF terminals are
closed, Hybrid Servo Controller
stops its output
Troubleshoot and press ”RESET”
When external EMG terminal is
not connected to the heating
switch of hybrid servo motor or the
motor is overheated (130
℃
),
Hybrid Servo Controller stops its
input
Troubleshoot and press ”RESET”
Abnormal brake crystal detected
by Hybrid Servo Controller
Press RESET. If the display still shows “bF”,
please send the unit back to manufacturer for
repair
