154 Parameters21.24 Smooth startcurrentCurrent used in the current vector rotation at low speeds.Increase the smooth start current if the application requiresmotor shaft swinging needs to be minimized. Note thataccurate torque control is not possible in the current vectorrotation mode.Can be used for permanent magnet synchronous motorsonly.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 isused. See parameter 21.19 Scalar start mode.Can be used for permanent magnet synchronous motorsonly.10.0%2.0…100.0% Value as a percentage of the nominal motor frequency. 1 = 1%21.26 Torque boostcurrentDefines the maximum supplied current to motor when (21.19Scalar 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 outputfrequency exceeds 40% of nominal frequency or when outputfrequency 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 ifparameter 95.04 Control board supply is set to External 24V.EnableDisable Force auto restart disabled. Parameter 21.18 Auto restarttime is in effect if its value is more than 0.0 s.0Enable Force auto restart enabled. Parameter 21.18 Auto restart timeis ignored. The drive never trips on the undervoltage fault andthe start signal is on forever. When he DC voltage is restored,the normal operation continues.12222 Speed referenceselectionSpeed 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 rpmValue of the selected speed reference.
