Before adjusting the drive and putting it into service, make sure that the motor

provided by the drive. The drive can be adjusted to operate the motor at
speeds above and below the speed provided by connecting the motor directly
to the power line.

if dangerous situations can occur. When activated, these functions will reset
the drive and resume operation after a fault.
Do not control the motor with the disconnecting device (means); instead, use
the control panel keys

power-ups by applying power) is five in ten minutes.
