Corrective action
• Check the command speed and
the number of pulses per
revolution/travel value per
revolution of the fixed
parameters.
• Check the connection of
SSCNET cable.
• Check if there is a disconnection
in the SSCNET cable.
• Check if the SSCNET cable is
clamped correctly.
• Check if any relays or solenoids
are operating in the vicinity.
• Check the connection of
SSCNET cable.
• Check if there is a disconnection
in the SSCNET cable.
• Check if the SSCNET cable is
clamped correctly.
• Set the DRU parameter correctly.
• Replace the servomotor.
• If the effective torque of the
stop
servomotor is high, reduce the
load.
• Reduce the frequency of
acceleration/deceleration.
• Check if the servo amplifier's fan
has stopped. (MR-H150B or
higher)
• Check if the passage of cooling
air is obstructed.
• Check if the temperature inside
the panel is too high (range: 0 to
°
+55[ C] (32 to 131[
• Check if the electromagnetic
brake was actuated from an
external device during
operation.
• Replace the servo amplifier.
• If the effective torque of the
servomotor is high, reduce the
load.
• Check the ambient temperature
of the servomotor (range: 0 to
°
+40[ C] (32 to 104[
• Replace the servomotor.
