Descriptions
MOTOR DATA MOTOR TYPE (99.03) Default: 1 (PMSM)
Range: 0, 1
0 Training Demo
1
Permanent magnet synchronous motor. Three-phase AC synchronous
motor with permanent magnet rotor and sinusoidal Back EMF voltage.
Selects the motor type.
Note: This parameter cannot be changed while the drive is running.
MOTOR CONTROL MODE
(99.04)
Default: 0 (DTC)
Range: 0, 1
0 Direct torque control. This mode is suitable for most applications.
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 identication (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.
1
Scalar control. The outstanding motor control accuracy of DTC cannot
be achieved in scalar control.
Refer to the DTC selection above for a list of applications where scalar
control should denitely be used.
Notes:
• 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 60), and section Operating
modes of the drive.
Selects the motor control mode.
MOTOR NOMINAL CURRENT
(99.06)
Default: 0.0 A
Range: 0.0 - 6400.0 A
Denes 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.
Note: This parameter cannot be changed while the drive is running.
BACK EMF VOLTAGE (99.07) Default: Back EMF
Range: 0.0 - 800.0
Denes the motor Back EMF voltage. This setting must match the value
on the auxiliary rating plate of the motor.
Notes:
• With permanent magnet motors, the nominal voltage is the Back EMF
voltage at nominal speed of the motor.
• The stress on the motor insulation is always dependent on the drive
supply voltage. This also applies to the case where the motor voltage
rating is lower than that of the drive and the supply.
• This parameter cannot be changed while the drive is running.
MOTOR NOMINAL
FREQUENCY (99.08)
Default: 0.0 Hz
Range: 0.0 - 500.0 Hz
Denes the nominal motor frequency. This setting must match the value
on the rating plate of the motor.
Note: This parameter cannot be changed while the drive is running.
