1. FUNCTIONS AND CONFIGURATION
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 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.
3. When a UL/C-UL-compliant servo motor is used in combination, the value is 2.9A.
4. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at an emergency stop and such conditions. Ensure the safety in the entire system.
