The proportional and integral gains of the speed adjustment loop and the response and propor tionnal gains of the current loop are factory preset to satisfy the majority of applications not requiring high performance levels For some special applications unusual divisions of inertia precise positioning it will be neces sary either to weaken or to reinforce the adjustment loop reactions by balancing the various gains Given the multiplicity of the applications it is impossible to specify adequate adjustments for each individual case These adjustments should be optimised on initial setting up using the directions on the following page Note Regarding the speed amplifier s proportional gain the configurable function G GO KN p 2 7 can extend these adjustments when very good proportional gain at low speed is required Obtaining high regulation performance is only possible with fast current loop responses which must always be adjusted first by the gains Always check that the dl dt obtained can be taken by the motor As an example the dl dt expressed in IN sec will be limited by dl In Nn s KO 60 for motors with solid frames dt SKO max Nmax With KO 200 for motors with laminated frames Field weakening adjustment See page 2 21 1 64 Initial setting up Dynamic adjustments Instructions for gain adjustments STABLE RIGID KI FAST KP e Current loop gains Fro
