ACS 300 User’s Manual 51
Chapter 7 - Drive Parameters
NOM FREQ
Nominal motor frequency from the motor rating plate (some-
times called the field weakening point). The maximum out-
put frequency of the ACS 300 is determined according to the
nominal motor frequency:
50-100 Hz => f
max
= 200 Hz; 101-400 Hz => f
max
= 500 Hz
NOM VOLT
Nominal motor voltage (from the motor rating plate). NOM
VOLT sets the maximum output voltage supplied to the
motor by the ACS 300. NOM FREQ sets the frequency
where the voltage to the motor is equal to NOM VOLT. With
these two parameters, it is possible to adapt the ACS 300 to
the motor.
The ACS 300 cannot supply the motor with a voltage greater
than the incoming line voltage. When driving a motor that
has a nominal voltage lower than the supply voltage, it may
not be possible to drive the motor at full torque because of
current limitations.
COS PHI
Power factor (Cos phi) of the motor from the motor rating
plate.
SUPPLY VOLT
Incoming power line supply voltage. This parameter exists
only in the 400 series units.
Note! NOM VOLT can only be set within ±20 V of SUPPLY
VOLT.
LANGUAGE
Select the preferred display language.
TEMP MOD
Calculated temperature of the motor as a percentage (%) of
nominal temperature. Motor temperature is calculated from
the motor current. MOTOR TEMP fault occurs when TEMP
MOD signal is equal to 115 %.
HOURS
Operation timer shows in hours how long the drive has been
running.
