354 Parameters
Selects the motor control mode.
DTC
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 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).

0
Scalar
Scalar control. The outstanding motor control accuracy of
DTC cannot be achieved in scalar control.
Refer to the
selection 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.
), and
section
1
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.
For ESP with sine filter and step-up transformer instead of
using the motor rating plate data, set the motor nominal
current according to the calculated current. See the
description of current calculation in section
on page
.
Note
:
• Correct motor operation 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.
