Display Code Description of Anomaly
Overheating of heat sink detected
by Hybrid Servo Controller,
exceeding the protection level (90
ºC).
(02-09 PTC level) Overheating
inside the motor drive detected by
Hybrid Servo Controller,
exceeding the protection level
(Pr02-09 PTC level).
IGBT overheated and unusual fan
function
Output current exceeds the
maximum capacity of Hybrid Servo
Controller
Servo motor overloaded
Chapter 5 Methods of Anomaly Diagnosis
1. Check if ambient temperature is too high.
2. Check if there is any foreign object on the
heat sink and if the fan is running.
3.Check if there is sufficient space for air
circulation for Hybrid Servo Controller
1. Check the control board, see if J7 is
switched to KTY84 but external terminals AUI
and CM don't receive signals from
KTY84-130.
2.Check if the motor drive is blocked
3.Check if the ambient temperature is too
high
4.Increase the capacity of the motor drive
Check the fan kit to see if it is blocked.
Return to factory for repair.
1. Check if the hybrid servo motor is stalled.
2. Check if the oil pump is stuck.
3. Such errors occur when the red light of PG
card flashes. The causes of these errors
could be loose contact/ disconnection
between encoder, motor drive and motor.
4. Set Pr00-04=29 (v2.06 and above),
observe if the value returns to zero after
every molding cycle. If the number
accumulates to 100, OL occurs.
5. Change the molding conditions.
6. Replace with the Hybrid Servo Controller
with larger output capacity.
1. Set Pr00-04=30 (v2.06 and above),
observe if the value returns to zero after
every molding cycle. If the number
accumulates to 100, EoL occurs.
Change the molding conditions.
2. Replace with the Hybrid Servo Controller
with larger output capacity,
3. If the pressure-flow is too high during
blending, such error occurs easily. To clear
this error, decrease the pressure command
and the flow command.
Note that this overload protection is only
available for version A motors.
