Asynchronous motor;
SynRM (95.21 b1);
Selects the motor type.
Note: This parameter cannot be changed while the drive
is running.
Motor type99.3
Permanent magnet
motor (95.21 b2) /
uint16
0Standard squirrel cage AC induction motor (asynchronous
induction motor).
Asynchronous motor
1Permanent magnet motor. Three-phase AC synchronous
motor with permanent magnet motor and sinusoidal
BackEMF voltage.
Permanent magnet
motor
2Synchronous reluctance motor. Three-phase AC
synchronous motor with salient pole rotor without
permanent magnets.
SynRM
DTC / uint16Selects the motor control mode.
Note: This parameter cannot be changed while the drive
is running.
Motor control mode99.4
0Direct torque control. This mode is suitable for most
applications.
DTC
Note: Instead of direct torque control, scalar control is also
available, and should be used in the following situations:
• 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).
See also section Operating modes of the drive (page 26).
1Scalar control. The outstanding motor control accuracy of
DTC cannot be achieved in scalar control.
Scalar
Refer to the selection DTC above for a list of applications
where scalar control should definitely be used.
Note:
• Correct motor operation requires that the magnetizing
current of the motor does not exceed 90% of the
nominal current of the inverter.
• Some standard features are disabled in scalar control
mode.
See also section Scalar motor control (page 63) and
section Operating modes of the drive (page 26).
