292 Parameters
Scalar Scalar control. Suitable for most applications, if top
performance is not required.
Motor identification run is not required.
Note: Scalar control must 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).
Note: Correct motor operation requires that the
magnetizing current of the motor does not exceed 90% of
the nominal current of the inverter.
See also section Speed control performance figures
(page 62), and section Operating modes of the drive
(page 46).

99.06 Motor nominal 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 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.
4.0 A
0.0…4.8 A Nominal current of the motor.
The allowable range:
• vector control mode: 1/6…2 × I
N
of the drive
• scalar control mode: 0…2 × I
N
of the drive.
Note: When using flying start in scalar control mode (see
parameter 21.19), the nominal current must be in the
range allowed for vector control mode.
1 = 0.01 A
(see par.
46.05)
99.07 Motor nominal voltage Defines the nominal motor voltage supplied to the motor.
This setting must match the value on the rating plate of
the motor.
Notes:
• With permanent magnet motors, the nominal voltage is
the BackEMF voltage at nominal speed of the motor. If
the voltage is given as voltage per rpm, e.g. 60 V per
1000 rpm, the voltage for a nominal speed of 3000 rpm
is 3 × 60 V = 180 V. Note that the nominal voltage is not
equal to the equivalent DC motor voltage (EDCM)
specified by some motor manufacturers. The nominal
voltage can be calculated by dividing the EDCM
voltage by 1.7 (or square root of 3).
• 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.
230.0 V
40.0…480.0 Nominal voltage of the motor. 10 = 1 V
