DEFINED F4
Defines the fourth frequency point of the custom U/f curve. 40.0 Hz
0.0…500.0 Hz Frequency 1 = 0.1 Hz
2618 FW VOLTAGE Defines the voltage of the U/f curve when frequency is equal
to or exceeds the nominal motor frequency (9907 MOTOR
NOM FREQ). See section Custom U/f ratio on page 133.

2619 DC
STABILIZER
Enables or disables the DC voltage stabilizer. The DC
stabilizer is used to prevent possible voltage oscillations in
the drive DC bus caused by motor load or weak supply
network. In case of voltage variation, the drive tunes the
frequency reference to stabilize the DC bus voltage and
therefore the load torque oscillation.

2901 COOLING FAN
TRIG
Defines the trigger point for the drive cooling fan run time
counter. Value is compared to parameter 2902 COOLING
FAN ACT value.
0.0 kh
0.0…6553.5 kh Time. If parameter value is set to zero, the trigger is
disabled.
1 = 0.1 kh
2902 COOLING FAN
ACT
Defines the actual value for the cooling fan run time counter.
When parameter 2901 COOLING FAN TRIG has been set
to a non zero value, the counter starts. When the actual
value of the counter exceeds the value defined by
parameter 2901, a maintenance notice is displayed on the
panel.
0.0 kh
0.0…6553.5 kh Time. Parameter is reset by setting it to zero. 1 = 0.1 kh
2903 REVOLUTION
TRIG
Defines the trigger point for the motor revolution counter.
Value is compared to parameter 2904 REVOLUTION ACT
value.
0Mrev
0…65535 Mrev Millions of revolutions. If parameter value is set to zero, the
trigger is disabled.
1 =
1Mrev
2904 REVOLUTION
ACT
Defines the actual value for the motor revolution counter.
When parameter 2903 REVOLUTION TRIG has been set to
a non zero value, the counter starts. When the actual value
of the counter exceeds the value defined by parameter
2903, a maintenance notice is displayed on the panel.
0Mrev
0…65535 Mrev Millions of revolutions. Parameter is reset by setting it to
zero.
1 =
1Mrev
2905 RUN TIME
TRIG
Defines the trigger point for the drive run time counter. Value
is compared to parameter 2906 RUN TIME ACT value.
0.0 kh
0.0…6553.5 kh Time. If parameter value is set to zero, the trigger is
disabled.
1 = 0.1 kh
