154 Parameters
21.24 Smooth start
current
Current used in the current vector rotation at low speeds.
Increase the smooth start current if the application requires
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 synchronous motors
only.
50.0%
10.0…100.0% Value in percent of the nominal motor current. 1 = 1%
21.25 Smooth start speed Output frequency up to which the current vector rotation is
used. See parameter 21.19 Scalar start mode.
Can be used for permanent magnet synchronous motors
only.
10.0%
2.0…100.0% Value as a percentage of the nominal motor frequency. 1 = 1%
21.26 Torque boost
current
Defines the maximum supplied current to motor when (21.19
Scalar start mode is set to Torque boost (see page 153).
Parameter value is in percent of the motor nominal current.
Nominal value of the parameter is 100.0%.
Torque boost is only applied at start, ending when output
frequency exceeds 40% of nominal frequency or when output
frequency is equal to reference.
Can be used in scalar mode only.
100.0%
15.0…300.0% Value in percent of the nominal motor current. 1 = 1%
21.34 Force auto restart Forces automatic restart. The parameter is applicable only if
parameter 95.04 Control board supply is set to External 24V.
Enable
Disable Force auto restart disabled. Parameter 21.18 Auto restart
time is in effect if its value is more than 0.0 s.
0
Enable Force auto restart enabled. Parameter 21.18 Auto restart time
is ignored. The drive never trips on the undervoltage fault and
the start signal is on forever. When he DC voltage is restored,
the normal operation continues.

22 Speed reference
selection
Speed reference selection; motor potentiometer settings.
See the control chain diagrams on pages 406…410.
22.01 Speed ref unlimited Displays the output of the speed reference selection block.
See the control chain diagram on page 407.
This parameter is read-only.
-
-30000.00…
30000.00 rpm
Value of the selected speed reference. See par.

22.11 Ext1 speed ref1 Selects Ext1 speed reference source 1.
A digital source selected by 19.11 Ext1/Ext2 selection can be
used to switch between Ext1 reference and the
corresponding Ext2 reference defined by parameter 22.18
Ext2 speed ref1,.
