The mains rectifier consists of an uncontrolled single or three-phase bridge connection, the single-phase design is restricted to small powers. Since during the charging of the DC-link capacitor very high currents flow for a short time which would lead to the tripping of the input fuses or even to the destruction of the mains rectifier, the charging current must be limited to a permissible level. This is achieved by using an inrush current limiting resistor in series to the capacitor. After the charging of the capacitor is completed the limiting resistor is bridged, for example, by a relay and is therefore only active at the switch-on of the inverter. As the smoothing of the DC-link voltage requires a large capacity, the capacitor still has a high voltage for some time after the disconnection of the inverter from the mains.

Netaxe These parameters represent absolute v4 values which in normal operation are not exceeded and which have no effect on the speed characteristic. Storing Parameter Values Page If the drive cannot follow the adjusted ramps,then the output switches in dependence on the setpoint value and not the actual value. The proportional factor of the position controller is adjusted in CS.

Page 89 Display of actual DC-link voltage. When display in rotations Pc. The setpoint is defined only by the setpoint signal at REF1. Set Value And Ramp Manuql If the drive cannot follow the adjusted ramps,then the output switches in dependence on the setpoint value and not the actual value. Page 29 2 X2. A conveyor belt shall be used with 3 different speeds. In the field weakening range larger tolerances are possible, also see reference on page 4 M [Nm] CP.

Sustained oscillation with high amplitude Solution: Power Supply Of Encoder Drive Curve Door Drive The AUX-function offers the possibility to add an analog setpoint to other setpoint settings or to use it as amplification factor for speed controller and torque limits.
