ACH550-02 User's Manual
9904 MOTOR CTRL MODE 1=VECTOR:SPEED,
3=SCALAR:FREQ
Selects the motor control mode.
1 =
VECTOR:SPEED – sensorless vector control mode
• Reference 1 is speed reference in rpm.
• Reference 2 is speed reference in % (100% is absolute maximum
speed, equal to the value of parameter 2002
MAXIMUM SPEED, or
2001
MINIMUM SPEED if the absolute value of the minimum speed is
greater than the maximum speed).
3 =
SCALAR:FREQ – scalar control mode
• Reference 1 is frequency reference in Hz.
• Reference 2 is frequency reference in % (100% is absolute
maximum frequency, equal to the value of parameter 2008
MAXIMUM
FREQ, or 2007 MINIMUM FREQ if the absolute value of the minimum
speed is greater than the maximum speed).
9905 MOTOR NOM VOLT 200…600 V
Defines the nominal motor voltage.
Must equal the value on the motor rating plate.
Sets the maximum drive output voltage supplied to the motor.
The ACH550 cannot supply the motor with a voltage greater than the
mains voltage.
9906 MOTOR NOM CURR type dependent
Defines the nominal motor current.
Must equal the value on the motor rating plate.
Range allowed: (0.2…2.0) · I
N
(where I
N
is drive current).
9907 MOTOR NOM FREQ 10.0…500 Hz
Defines the nominal motor frequency.
Range: 10…500 Hz (typically 50 or 60 Hz)
Sets the frequency at which output voltage equals the
MOTOR NOM
VOLT.
Field weakening point = Nom freq · Supply Volt / Mot Nom Volt
9908 MOTOR NOM SPEED 50…30000 rpm
Defines the nominal motor speed.
Must equal the value on the motor rating plate.
