Torque
saturation
anomaly
protection
Torque saturated has continued for the
period set to Pr 7.16 “Torque saturation
error protection frequency” or Pr6.57
“Torque saturation anomaly detection
time”. • Check the operating state of the driver.
• Take the same measure as done against
Err16.0.

Over-
regeneration
load
protection
Regenerative energy has exceeded the
capacity of regenerative resistor.
1) Due to the regenerative energy during
deceleration caused by a large load
inertia, converter voltage has risen,
and the voltage is risen further due to
the lack of capacity of absorbing this
energy of the regeneration discharge
resistor.
2) Regenerative energy has not been
absorbed in the specified time due to a
high motor rotational speed.
3) Active limit of the external regenerative
resistor has been limited to 10 % duty.
Caution
Install an external protection such as thermal fuse without fail when
you set up Pr0.16 to 2. Otherwise, regenerative resistor loses the
protection and it may be heated up extremely and may burn out.
Check the load factor of the regenerative
resistor from the front panel or via communi-
cation.
Do not use in the continuous regenerative
brake application.
1) Check the running pattern (velocity
monitor). Check the load factor of the
regenerative resistor and over-regeneration
warning display. Increase the capacity
of the driver and the motor, and loosen
the deceleration time. Use the external
regenerative resistor.
2) Check the running pattern (speed monitor).
Check the load factor of the regenerative
resistor. Increase the capacity of the driver
and the motor, and loosen the deceleration
time. Lower the motor rotational speed.
Use an external regenerative resistor.
3) Set up Pr0.16 to 2.

error
protection
Communication between the encoder
and the driver has been interrupted
in certain times, and disconnection
detecting function has been triggered. Make a wiring connection of the encoder as
per the wiring diagram. Correct the miswiring
of the connector pins.

Encoder
communication
error
protection
Communication error has occurred in
data from the encoder. Mainly data
error due to noise. Encoder cables are
connected, but communication data has
some errors. • Secure the power supply for the encoder
of DC4.90 V to 5.25 V)...pay an attention
especially when the encoder cables are
long.
• Separate the encoder cable and the motor
cable if they are bound together.
• Connect the shield to FG.
Caution
Note
・
Confirmation work is that checking the charge lamp is turned off after the power supply turn off.
・
When protective function marked with * in the protective function table is activated, it cannot
be disabled by the alarm clear input (USB conmmunication(PANATERM) or RTEX alarm
clear commond). To return to the normal operation, turn off power, and then turn on power
again,or use soft reset commond by RTEX conmmunication.
