Error counter overflow
Occurs when the control
power is turned ON.
• During the initialization
of position data, the
value that is obtained
by dividing the
Absolute encoder
position (pulse unit) by
the Electronic gear
ratio exceeded
2
31
(or
2147483648).
• Review the operation
range of Absolute
encoder position and
the electronic gear
ratio.
Occurs during operation.
• The error counter value
for the encoder pulse
reference exceeded
2
29
(536870912).
• Check that the motor
rotates in accordance
with the position
command.
• Check that the output
torque is not saturated
on the torque monitor.
• Adjust the gain.
• Maximize the set
values on the No.1
Torque Limit (Pn013)
and the No2. Torque
Limit (Pn522).
• Wire the encoder
correctly.
• The position error in
command unit
exceeded
