Code
Possible Cause Countermeasures
 Check the values of the
regenerative resistor.
E.079
Regenerative
Over Current
Protection
E.SHtoC 0x2211 0x12
The regenerative current exceeds
the allowable instant value.

Check if the regenerative resistor is
shorted or damaged.
 Check if the overload energy is
excessive while decelerating.
E.083
Low Battery Error
of Absolute
Encoder
E.AbSbE 0x6320 0x33
The parameter of the encoder
backup battery is set as ‘installed,’
but the battery is not installed.
 Set the constant of the encoder
backup battery as ‘not installed.’
The battery voltage is detected
under 2.7 [V] DC.
 Check the battery voltage and the
connections.

Replace the battery.
E.084
Absolute Encoder
Over Speed
E.AbSoS 0x7310 0x34
The encoder rotates mechanically
at high speed while the drive
power turns off, when it is
powered by the battery.  Remove the motor from the
system.
 Turn off and on the drive and reset
the Warning.
E.085
Absolute Encoder
Multi-turn Count
Error
E.MtCEr 0x7300 0x35
Noise from Encoder

Turn off and on the drive and reset
the Warning.
Defective Encoder
Multi rotation data is abnormal

Replace the motor.
E.101
Motor Power
Cable Open
E.CAbLE 0x7122 0x20 The motor cable is not connected.
 Check the power connection
between the motor and the drive.
E.102
Motor
instantaneous
current overload
E.InSoL 0x8331 0x21
The motion profile requires peak
current over 300% for a few
second.
 Check the wiring of the motor.
 Adjustthe cceleration/deceleration
time.
 Check if the motor selected is
suitable.
There is a defect in the current
feedback detection.
 Check the phase current of motor
E.103
Motor Mismatch
Fault
E.MAtCH 0x6320 0x28
The dynamic control current of the
selected motor exceeds double
the value of the drive peak current
rating.
 Replace the motor with
appropriate motor.
E.106
Encoder
Communication
Error
E.EnCCE 0x7300 0x32
The wiring between the drive and
the encoder is cut off or
problematic. Or encoder signals
are interrupted by the EMI (noise).

Check the wiring of the encoder.

Contact your nearest dealer.
E.107
Serial
Communication
Error
E.SErCE 0x7510 0x60
Communication error between the
host and the drive (noise)
 Check the serial communication
cable.
 Check the noise of the serial
communication interface.
E.111
Safety Torque Off
Input Error
E.StoIn 0x7121 0x56
The Safety Torque Off input is
open. (Normal Close input
condition)
 The signal was inputted by STO
input. Set the release condition.
 Check the STO connection.
 Check the connection of the
dummy connector provided with
the product.
