E21
The hybrid motor
drive detects
excessive output
current (oL)
1. Check if the hybrid servo motor is
stalled.
2. Replace the hybrid servo drive with a
larger output capacity model.
3. Set Pr00-04=29, observe if the value
returns to zero after every molding
cycle. If the number accumulates to
100, OL occurs
4. The causes of this error could be
loose contact/ disconnection between
encoder, servo drive and the motor.
This error also occurs when a motor
or an oil pump is stalled which make
unusual rotating speed and over
current.

E22
Servo motor
overload (EoL1)
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 drive
with a larger output capacity model.
3. If the pressure –flow is too high
during the blending, such error
occurs easily. To clear this error,
decrease the pressure command and
the flow command.

(02-09 PTC
level)
Overheating
inside the motor
drive detected by
hybrid servo
drive, exceeding
the protection
level (Pr02-09
PTC level)
(oH3).
1. Check if the motor drive is blocked.
2. Check if the ambient temperature is
too high.
3. Increase the capacity of the motor
drive.
