In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance work.
The power is turned on during maintenance where any servo-axis must be operated or machine operation
must be checked. In this case, also ensure adequate safety before beginning the maintenance.
When operating the machine, make sure the following conditions are satisfied.
