• Change the slot of the servo
amplifier whose load is large.
• Reduce the load.
• Reexamine the operation pattern.
• Use a servomotor whose output is
large.
• Repeat acceleration/deceleration
and perform automatic tuning.
• Turn off automatic tuning and
stop
make gain adjustment manually.
• Make correct connection.
• Remove the alarm causes of all
servo amplifiers where alarm has
occurred.
• Check for disconnection of the
cable.
• Replace the communication
devices.
• Replace the battery.
• Replace the battery.
• Check the encoder cable for wire
breakage.
• Replace the servomotor.
