2.5 Restrictions when using this product at an altitude
exceeding 1000 m and up to 2000 m
For restrictions on the drive unit/servo amplifier, refer to the drive unit/servo amplifier user's manual and instruction manual.
Effective load ratio and regenerative load ratio
As heat dissipation effects decrease in proportion to decreasing air density, use the product within the effective load ratio and
regenerative load ratio shown in the following figure.
Input voltage
Generally, withstand voltage decreases as altitude increases; however, there is no restriction on the withstand voltage.
Parts with a service life
■Smoothing capacitor
The capacitor will reach the end of its service life in 10 years of continuous operation in an air-conditioned environment (with
an ambient temperature of 30 °C or less).
■Converter unit cooling fan
There is no restriction.
