Excitement
detection error
Cause : The excitation detection starts when
the servo is turned on for the first time
after the power is supplied. Detection
process does not complete in the
specific time (set in Parameter No.29 if
Positioner Mode 1, Positioner Mode 2
or Pulse Train Control Mode).
1) Connection error or wire breakage
of motor/encoder cables.
2) Brake is not released (when
equipped with a brake).
3) Load to the motor is high due to
external force.
4) Power was turned on while touching
to the mechanical end.
5) The resistance in the actuator
sliding operation is large.
6) In the case of Positioner Mode 1,
Positioner Mode 2 or Pulse Train
Control Mode, a smaller number
than the initial value was set in
Parameter No.22 Home-Return
Offset.
In the case of MEC Mode 1 or MEC
Mode 2, a smaller number than the
initial value was set in Parameter
No.16 Home-Return Offset.
Treatment : 1) Check for the motor/encoder cable
wiring condition.
2) For Positioner Mode 1 and MEC
Mode 1, if the problem is solved
with 24V DC 150mA being supplied
to BK, it may be concerned a
malfunction of the controller inside
the ERC3 motor unit.
3) Confirm that there is no error in the
mechanical part assembly
condition.
4) Move the slider or the rod to a point
where it would not hit the
mechanical end and reboot the
system.
5) If the loaded weight is within the
allowable range, turn the power
OFF and check the resistance in
sliding operation by moving the
slider with hand.
6) In the case of Simple Absolute
Type, the excitation detection is
executed again at the home-return
complete. If the Parameter No.22
Home Return Offset is set smaller
than the initial setting, the actuator
interferes with the mechanical end
and excitation detection cannot be
performed properly.
