Operation with increased power at a 500 V mains
The controller can be operated with increased continuous power (120% P
aN
) on a more
powerful motor. The overload capacity remains constant as if operated with a continuous
power of 100%; the information about the percentage values provided for the overload
phases still refers to rated data of 100%. Typical application cases include drives for units
with quadratic load characteristics such as pumps and fans.
Note!
Operation with increased power is only permitted ...
