Input Power Supply, Molded-case Circuit Breaker, and Fuse
Use input power supplies that meet the following conditions.
• The main circuit power supply must be a 24-VDC or a 48-VDC power supply.
• The control circuit power supply must be a 24-VDC power supply.
• The main circuit power supply and the control power supply must be two separate input power supplies.
• Power supplies must have double or reinforced insulation that conforms to safety standards.
• Power Supply Capacity and Wire Size
∗
The value that is given is for the maximum instantaneous load.
Note: The specified maximum applicable servomotor capacity, specified power supply capacity, and specified input cur-
rent capacity for the main circuit power supply are per axis. The power supply capacity will be the given value mul-
tiplied by the number of controlled motor axes.
• Molded-case Circuit Breaker and Fuse Capacities
Select the molded-case circuit breaker and fuse for the AC side of the input power supply according to the
power supply specifications that you will use.
