Note 1. This value is applicable when a 3-phase power supply is used.
2. The current capacity 0.3 A is applicable when all I/O signals are used. The current capacity can be decreased by reducing the
number of I/O points. For the servo amplifiers manufactured in April 2016 or earlier (or manufactured in China in May 2016 or
earlier), the current capacity 0.1 A is applicable.
3. The communication cycle depends on the controller specifications and the number of axes connected.
4. When closely mounting the servo amplifiers, operate them at the ambient temperature of 0 °C to 45 °C or at 75% or smaller
effective load ratio.
5. When using 1-phase 200 V AC to 240 V AC power supply, operate the servo amplifier at 75% or smaller effective load ratio.
6. Follow the restrictions in section 2.7 when using this product at altitude exceeding 1000 m and up to 2000 m above sea level.
