Actual signals and parameters 237
2621 SMOOTH
START
Selects the forced current vector rotation mode at low
speeds. When the smooth start mode is selected, the rate of
acceleration is limited by the acceleration and deceleration
ramp times (parameters 2202 and 2203). If the process
driven by the permanent magnet motor has high inertia,
slow ramp times are recommended.
Can be used for permanent magnet motors only.
NO
NO Disabled 0
YES Enabled 1
2622 SMOOTH
START CUR
Current used in the current vector rotation at low speeds.
Increase the smooth start current if the application requires
high pull-up torque. Decrease the smooth start current if
motor shaft swinging needs to be minimized. Note that
accurate torque control is not possible in the current vector
rotation mode.
Can be used for permanent magnet motors only.
50%
10…100% Value in percent of the motor nominal current 1 = 1%
2623 SMOOTH
START FRQ
Output frequency up to which the current vector rotation is
used.
Can be used for permanent magnet motors only.
10%
2…100% Value in percent of the motor nominal frequency 1 = 1%
29 MAINTENANCE
TRIG
Maintenance triggers
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
