436 Parameters
Selects the motor control mode.
Note:
This parameter cannot be changed while the drive is
running.
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).
(page
).
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.
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.
(page
), and section
(page
).
1
Defines the nominal motor current. This setting must match
the value on the rating plate of the motor. If multiple motors
are connected to the drive, enter the total current of the
motors.
Notes:
• 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.
0.0 A
0.0 … 6400.0 A
Nominal current of the motor. The allowable range is 1/6…2 ×
I
N
(nominal current) of the drive (0…2 ×
I
N
with scalar control
mode).
1 = 1 A
