0.5A 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.
When closely mounting the servo amplifier of 3.5 kW or less, operate them at the ambient temperatures of 0 ÛC to 45 ÛC or at
75% or smaller effective load ratio.
This function diagnoses malfunction of contacts including an external circuit by shortly turning off signals from a controller to
the servo amplifier at a constant period while input signals of the servo amplifier are on.
Except for the terminal block.
The rated current is 2.9 A when the servo amplifier is used with UL or CSA compliant servo motor.
Available in the future.
