8.6 Carrying out the first test runWarning!Operating synchronous motors without encoder offset can cause uncontrolled motor movementsAn encoder offset adjustment must be made in synchronous motors before starting the first time (seechapter "Special Functions")!The offset calibration has already been performed in the factory for ZIEHL-ABEGG motors.If third-party motors are used, the offset must be performed as follows (obtain information frommanufacturer): Connect motor winding to DC voltage: U R + and V and W R -. Offset value = 0The first trip must be carried out with the return control or as an inspection trip.If this trip can be carried out without any problems and without any fault messages, a normal trip canbe made as the next step.If fault messages appear, an error list is available in the “Diagnose” chapter together with thecorresponding error causes8.7 Optimisation of the startup and drive behaviourThe "SPD_KP" (amplification) parameter can be used to optimise the setting of the speed controlleracting during travel. The parameter can be changed in the Control/SPD_KP menu.Control|-" SPD_KP 1.00|-" 0.95Speed controller basicgainYou can generally set the speed control by changing the factor for the basic amplification ("SPD_KP").If significant control deviations occur during the trip (especially during acceleration and deceleration),(see Fig.), the amplification has been set too low. In this case, increase the factor for amplification("SPD_KP").´Control deviations when the amplification is set too lowblue Set-value - travel speedred Actual-value - travel speedOriginal operating instructionsZETADYN 3C Start-upR-TBA08_03-GB 1619 Part.-No. 00163322-GB63/204
