Check that the motor operates per the
position command pulse. See the torque
monitor to check that the output torque
does 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.
