The properties of the speed controller can be adapted for adjustment and optimizationof the controller. The amplification and integral time of the speed controller are to beset via parameters Amplification 1 721 and Integral Time 1 722. For the secondspeed range, parameters Amplification 2 723, Integral Time 2 724 can be set. Thedistinction between the speed ranges is done by the value selected via parameterSpeed Control Switch-Over Limit 738. The parameters Amplification 1 721 and Integraltime 1 722 are taken into account in the case of the default parameter SpeedControl Switch-Over Limit 738. If parameter Speed Control Switch-Over Limit 738is set to a value higher than 0.00 Hz, parameters Amplification 1 721, Integral Time1 722 are active below the limit and parameters Amplification 2 723, Integral Time 2724 are active above the limit.The parameterized amplification at the current operating point can additionally beassessed via the parameter Backlash Damping 748 depending on the control deviation.In particular the small signal behavior in applications with a gearbox can be improvedby a value higher than zero percent.The parameter Backlash damping 748 is available depending on the device type.ParameterSettingsNo. Description Min.

This enables a first function test in a large number of applications.The distinction of the parameter settings 1 or 2 for the current frequencyrange is done by the software according to the selected limit value.The optimization of the speed controller can be done with the help of a referencevalue step-change. The amount of the step-change is defined by the set ramp or limitation.The optimization of the PI controller should be done at the maximum admissiblereference value change rate. First, the amplification is increased until the actualvalue overshoots distinctly during the control process. This is indicated by a strongoscillation of the speed and by the running noises. In the next step, reduce the amplificationslightly (1/2 ...3/4 etc.). Then reduce the integral time (larger I component)until the actual value overshoots only slightly in the control process.If necessary, check the speed control settings in the case of dynamic operations (acceleration,deceleration). The frequency at which a switch-over of the controller parametersis effected can be set via parameter Speed Control Switch-Over Limit 738.16.5.3.1 Limitation of Speed ControllerThe output signal of the speed controller is the torque-forming current componentIsq. The output and the I component of the speed controller can be limited via parametersCurrent Limit 728, Current Limit Generator Operation 729, Torque Limit730, Torque Limit Generator Operation 731 or Power Limit 739, Power Limit GeneratorOperation 740. The limits of the proportional component are set via parameterP-Comp. Torque Upper Limit 732 and parameter P-Comp. Torque Lower Limit 733.−The output value of the controller is limited by an upper and a lower current limit,parameter Current Limit 728 and parameter Current Limit Generator Op. 729.The limit values are entered in Amperes. The current limits of the controller canbe linked to the fixed limits and analog input parameters. The assignment is donevia the parameters Isq Limit Source Motor Op. 734 and Isq Limit Source GeneratorOp. 735.156 02/06
