Technical data

Operation with increased rated power

Under the application conditions described here the controller can be operated in
continuous operation with a motor of higher performance. The overload capacity is
reduced to 120 %.
Typical applications are pumps with square−law load characteristic or blowers.
)
Note!
Operation with increased rated power is only permissible
with the drive controllers mentioned
l
within the mains voltage range mentioned
l
with the chopper frequency mentioned
l
with the prescribed fuses, cable cross−sections and mains chokes
