Countermeasures
Check that the motor operates per the
position command pulse. See the torque
monitor to check that the output torque
doe
s not get saturated. Readjust the gains.
Maximize the value of Pr5E (torque limit set-
up). Correct the encoder wiring.
Set all the parameters again. If this error
occurs frequently, the amplifier may have
been broken. Replace the amplifier with a
new one. Return the old amplifier to the
sales agent for repair.
The amplifier may have been broken.
Replace the amplifier with a new one. Return
the old amplifier to the sales agent for repair.
Check the switches, wires and power
supply that constitute the circuits. Check
that the control power (12 to 24VDC) can
be established without delay. Check the
value of Pr04. Correct the wiring, if
necessary.
Turn off the power and turn it on again. If
the error cannot be eliminated, the motor
and/or amplifier may be broken.
Discontinue use of the motor, and replace
the motor and the amplifier. Return the old
equipment to the sales agent for repair.
Cause
The value of the position error counter is
over 2
27
(134217728).
The data contained in the parameter stor-
age area of the EEPROM is broken,
The check code of the EEPROM is bro-
ken,
Both the CW and CCW over-travel limits
are not active.
The control circuit operates incorrectly
due to large noises or any other reasons.
The amplifier's self-diagnosing function is
activated, because an error happens in
the amplifier.
