4.2.6 Operation with increased power at a 400 V mains

The controller can be operated with i ncreased continuous power (120% P

)onamore

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 ...

ƒ With the rated data provided for the controller.

ƒ In the stated mains voltage range.

ƒ At switching frequencies of 2 kHz and 4 kHz.

ƒ At a max. ambient temperature of 40 °C.

ƒ With the stated installation types.

ƒ With the fuses, cable cross-sections, mains chokes and filters required for

this type of operation.

ƒ After parameterisation acc. to specification (cp. software manual
