Note 1. 0.3A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of
I/O points.
2. When closely mounting the driver of 3.5kW or less, operate them at the ambient temperatures of 0 to 45
or at 75% or smaller
effective load ratio.
3. When a UL/C-UL-compliant servo motor is used in combination, the value is 2.9A.
