ABB ACQ80-04 User Manual

Parameters 175
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 systems 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 section Operating modes of the drive (page 31).
1
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.
1.8 A
0.0 …5.2 A Nominal current of the motor. The allowable range is 1/6…2 ×
I
N
of the drive (0…2 × I
N
with scalar control mode).
1 = 1 A
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.
• 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.
400.0 V
69.2...830.0 V Nominal voltage of the motor. 10 = 1 V
99.08 Motor nominal
frequency
Defines 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.
50.0 Hz
0.0…500.0 Hz Nominal frequency of the motor. 10 = 1 Hz
99.09 Motor nominal
speed
Defines the nominal motor speed. The setting must match the
value on the rating plate of the motor.
Note: This parameter cannot be changed while the drive is
running.
1430 rpm
0…30000 rpm Nominal speed of the motor. 1 = 1 rpm
