CE marking
See 1-2-1, “Safety standards”, and Chapter 3, “EMC Countermeasures”.
*1: When controlling a brake and I/O operations, a separate 24V power supply with a necessary capacity must be connected to the I/O connectors.
The robot performance may be enhanced if a 24V power supply with an adequately large capacity is available. Please consult us for more details.
*2: When no brake and I/O control are used. An additional power supply will be needed to provide power for the brake and I/O control
