2.7 Restrictions when using this product at altitude exceeding 1000 m and up to 2000 m above sea level
(1) Effective load ratio and regenerative load ratio
As heat dissipation effects decrease in proportion to the decrease in air density, use the product within
the effective load ratio and regenerative load ratio shown in the following figure.

[m]
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. (Refer to section 2.1.)
(2) Input voltage
Generally, a withstand voltage decreases as increasing altitude; however, there is no restriction on the
withstand voltage. Use in the same manner as in 1000 m or less. (Refer to section 1.3.)
(3) Parts having service life
(a) Smoothing capacitor
The capacitor will reach the end of its life in 10 years of continuous operation in air-conditioned
environment (ambient temperature of 30 °C or less).
(b) Relay
There is no restriction. Use in the same manner as in 1000 m or less. (Refer to section 2.6.)
(c) Servo amplifier cooling fan
There is no restriction. Use in the same manner as in 1000 m or less. (Refer to section 2.6.)
