Temperature Compensation
In case of higher ambient temperature use the following formula:
(Ambient temperature - 20) x 0.125 = correction factor in % of the
full load motor current
Example:
Ambient temperature 70°C, full load motor current 7A
(70 - 20) x 0.125 = 6.25%
Setting value: 7A + 6,25% = 7.44A
