• With default settings of b1-14 = 0, the drive puts out voltage in U-V-W phase sequence when a Run command is input.
Check the motor rotation with this phase sequence (for most motors clockwise seen from the shaft side). Disconnect
the motor from the pump if possible or set a slow speed which will not cause problems to the pump while giving the
Run command.
• If the pump flow is correct with a U-V-W sequence, keep parameter b1-14 set to 0.
• If the pump flow is incorrect with a U-V-W sequence, set parameter b1-14 to 1.
Note: Always perform motor rotation direction setup prior to setting the encoder rotation direction.
 Digital Operator Display Unit Selection
The drive allows to choose between different display units for speed related parameters and monitors, acceleration and
deceleration ramps and jerk settings. The units can be selected using parameter o1-03 like shown below.
 Motor Data and Encoder Auto-Tuning
 Auto-Tuning Types
Auto-Tuning automatically programs the drive’s motor and motor control related parameters. Select between
Auto-Tuning methods listed below.
Motor Data Tuning Modes for Induction Motors
 Tuning Mode Selection and Data Input
For Auto-Tuning, enter the Auto-Tuning menu (via the T parameters) and perform the steps shown in the figure below.
Data required from the motor nameplate will vary depending on the type of Auto-Tuning selected. This example shows
the procedure for performing Rotational Auto-Tuning of an induction motor.

Type Setting Requirements and Benefits
Rotational Auto-Tuning
T1-01 = 0
• Rotational Auto-Tuning gives the most accurate results, and is therefore highly recommended if
possible.
• Motor must run freely or with light load (<30%), i.e. ropes have to be removed.
Stationary Auto-Tuning 1
T1-01 = 1
• Automatically calculates motor parameters needed for vector control.
• Use if ropes cannot be removed. Note that the accuracy is less then with Rotational Auto-tuning.
Stationary Auto-Tuning for
Line-to-Line Resistance
T1-01 = 2 • Used when the drive was set up properly before and the motor cable has changed.
Stationary Auto-Tuning 2
T1-01 = 4
• A motor test report is available. The no-load current and the rated slip have must be entered from the
test report, all other motor-related parameters are calculated automatically.
• Use if ropes cannot be removed and if slip and no-load current data are available.
