31 F600 Step By Step Guide
Drive Operating modes
Open-loop (OL) mode
The drive operating mode is set using Pr 0.004, by selecting either “Induction” or “Permanent-
magnet” and pressing the red OFF / Reset button.
Selecting “Induction” sets the drive into Open-loop (OL) mode and selecting “Permanent-magnet”
sets the drive into RFC-S sensorless mode, which are the most common operating modes used.
The drive supports the following operating modes:
Open-loop (OL) mode for use with an induction motor
The drive applies power to the motor at frequencies varied by the user. The motor speed is a result of
the output frequency of the drive and slip due to the mechanical load.
RFC-A mode for use with an induction motor with feedback device
The drive directly controls the speed of the motor using the feedback device. The motor flux is
accurately controlled to provide full torque down to zero speed.
Synchronous permanent magnet brushless motor without feedback
(RFC-S sensorless mode)
Flux control is not required because the motor is self-excited by the permanent magnets which form part
of the rotor. Full torque is available down to zero speed, with salient motors. Position information from
the sensorless algorithm is used to ensure the output voltage is matched to the back EMF of the motor.
Synchronous permanent magnet brushless motor with feedback device
(RFC-S feedback mode)
The drive directly controls the speed of the motor using the feedback device. Flux control is not
required because the motor is self-excited by the permanent magnets which form part of the rotor.
Position information is required from the feedback device to ensure the output voltage is accurately
matched to the back EMF of the motor. Full torque is available down to zero speed.
Stop the motor
when finished.
Stop the Motor by pressing the red OFF / Reset button for or by opening the Hand switch.
The pump software status changes to Off (Ready).
Save the drive
parameters.
Set Pr 0.000 to “Save Parameters” and press the red OFF / Reset button.
Choose the
operating mode and
additional features.
Set Pump Control Mode Pr 0.021 to match the system. The options available are Single
Pump, Cascade and Multi-leader.
Configure the Pump system features required. See the user guide functional description
section or the Basic Features section for more details on the on the control modes and
features available.
