Absolute System Fault Messages
: Voltage level above specification
Potential Cause
The voltage level of
the battery is higher
than the specified
voltage ( > 3.8V).
: Gray code error
Potential Cause
An absolute position
error within one
turn.
: Absolute position lost
Potential Cause
The voltage level of
the battery is too
low.
The initialization
procedure of an
absolute system has
not finished after
enabling the
absolute function.
Bad connection or an
open circuit
occurred in the
wiring between the
battery box and the
servo drive.
: Voltage level below specification
Potential Cause
The voltage level of
the battery is too
low.
10-30
Checking Method
1. Check if an electrical charge still
remains in the servo drive.
2. Examine the installation of the
battery.
Checking Method
Power ON the drive and turn the
connected motor again to check if this
fault message will disappear.
Checking Method
Check if the voltage level of the battery
is lower than 2.7V.
1. Install a battery box.
2. Check the wiring connection between
the battery box and the servo drive.
3. Check if the wiring is correct of the
encoder.
1. Check the wiring connection between
the battery box and the servo drive.
2. Check if the wiring is correct of the
encoder.
Checking Method
1. Check if the voltage level of the
battery that is displayed on the
keypad is lower than 3.1 V.
2. Measure if the voltage level of the
battery is lower than 3.1 V.
Chapter 10 Troubleshooting
Corrective Actions
This fault message can be
removed automatically after
the voltage level has returned
within its specification.
Corrective Actions
If this fault message cannot
be clear by restarting the
servo system, replace the
encoder.
Corrective Actions
Replace the battery and
execute the homing procedure
again. Please refer to section
12.3.4 to 12.3.5 for
initialization procedure of an
absolute system.
Execute the homing procedure
again. Please refer to section
12.3.4 to 12.3.5 for
initialization procedure of an
absolute system.
Conduct the wiring again.
Then, execute the homing
procedure again. Please refer
to section 12.3.4 to 12.3.5 for
initialization procedure of an
absolute system.
Corrective Actions
Replace the battery when the
control power is applied to the
servo drive. This fault
message can be removed
automatically after conducting
battery replacement.
