Code Error Cause/action
0ED Absolute encoder error (1) Cause: [1] When the power was turned off and then on again following an absolute
reset, the current position changed due to an external factor, etc., while
the controller was communicating with the absolute unit.
[2] When an absolute reset was executed, the current position changed
due to an external factor, etc., while the controller was communicating
with the absolute unit.
Action: [1] When the detail code is H’0001:
Turn off the power and then turn it back on in a condition where the
actuator is not receiving vibration, etc.
[2] When the detail code is H’0002:
Perform homing again in a condition where the actuator is not receiving
vibration, etc.
0EE Absolute encoder error (2) Cause: [1] The power has been turned on for the first time after the battery was
connected to the simple absolute unit.
[2] When the detail code is H’0001:
The battery voltage has dropped to a level where the encoder counter in
the simple absolute unit can no longer retain data.
[3] When the detail code is H’0002:
The encoder connector was unplugged during a power outage, or the
encoder cable became disconnected.
[4] When the detail code is H’0003:
A related parameter was changed.
Action: If [1], [3] or [4] is the case, perform an absolute reset by referring to the
operation manual for the simple absolute unit (5.2, “How to Perform an
Absolute Reset”).
If [2] is the case, supply power for at least 48 hours to fully charge the
battery, and then perform an absolute reset.
0EF Absolute encoder error (3) Cause: The current value has changed at a speed corresponding to or exceeding
the rotational speed setting, due to an external factor, etc., while the power
was cut off.
Action: Change the applicable setting of the simple absolute unit and also
implement measures to prevent the actuator from moving at a speed
corresponding to or exceeding the set speed while the power is cut off.
When the battery has enough retention time, set the motor speed setting
high.
Reference: Refer to: 5.1.1, “Piano Switch Settings” in the operation manual for the
simple absolute unit.
Should this error occur, perform an absolute reset according to the
specified procedure (5.2, “How to Perform an Absolute Reset”).
