99.04 Motor type Selects the motor type.
Note: This parameter cannot be changed while the drive is
running.
AM Asynchronous motor. Three-phase AC induction motor with
squirrel cage rotor. 0
PMSM Permanent magnet motor. Three-phase AC synchronous
motor with permanent magnet rotor and sinusoidal BackEMF
voltage. 1
99.05 Motor ctrl mode Selects the motor control mode.
DTC Direct torque control. This mode is suitable for most
applications.
Note: Instead of direct torque control, use scalar control
• with multimotor applications 1) if the load is not equally
shared between the motors, 2) if the motors are of different
sizes, or 3) if the motors are going to be changed after the
motor identification (ID run),
• if the nominal current of the motor is less than 1/6 of the
nominal output current of the drive,
• if the drive is used with no motor connected (for example,
for test purposes),
• if the drive runs a medium-voltage motor through a step-up
transformer.
0
Scalar Scalar control. This mode is suitable in special cases where
DTC cannot be applied. In scalar control, the drive is
controlled with a frequency reference. The outstanding motor
control accuracy of DTC cannot be achieved in scalar control.
Some standard features are disabled in scalar control mode.
Note: Correct motor run requires that the magnetizing current
of the motor does not exceed 90% of the nominal current of
the inverter.

99.06 Mot nom current Defines the nominal motor current. Must be equal to the value
on the motor rating plate. If multiple motors are connected to
the drive, enter the total current of the motors.
Notes:
• Correct motor run requires that the magnetizing current of
the motor does not exceed 90% of the nominal current of
the drive.
• This parameter cannot be changed while the drive is
running.
