Note 1. 150mA 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 servo amplifier of 3.5kW or less, operate them at the ambient temperatures of 0 to 45
or at 75%
or smaller effective load ratio.
