Description of Fault Codes
‑90‑
Cause
Confirming Method
Solution
The lower limit of the
software position limit is
equal to or larger than the
upper limit.
Check the values of
607D.01h and 607D.02h.
Reset the values and ensure
the former is smaller than
the latter.
● EE09.1: Home setting error
Cause:
The home offset exceeds the upper/lower limit.
Cause
Confirming Method
Solution
1. The home offset is outside
the software position limit.
The home offset is outside
the software position limit
when the encoder works in
the incremental mode,
absolute linear mode, and
single‑turn absolute mode.
Set the home offset to a
value within the software
position limit.
2. The home offset is beyond
the upper/lower limit in the
rotation mode.
The home offset is outside
the mechanical single‑turn
upper/lower limit when the
encoder works in the
rotation mode.
Set the home offset to a
value within the mechanical
single‑turn upper/lower
limit.
● EE09.2: Gear ratio beyond the limit
Cause:
The electronic gear ratio exceeds the limit: (0.001, 4000 x Encoder resolution/
10000).
Cause
Confirming Method
Solution
The set electronic gear ratio
exceeds the preceding
range.
The gear ratio 6091.01h/
6091.02h exceeds the
preceding range.
Set the gear ratio according
to the preceding range.
● EE09.3: No synchronization signal
Cause:
The MCU does not receive the synchronization signal when the servo
communication is switched to OP status.
Cause
Confirming Method
Solution
1. The communication
synchronization clock is
configured improperly.
Replace with another master
(such as Beckhoff or Omron
PLC) and perform tests to
compare between different
masters.
Rectify improper
configurations.
2. The communication IN
and OUT ports are
connected inversely.
Check the connection of the
IN and OUT ports.
Connect the IN and OUT
ports in the correct
sequence.
