Setting Parameters01/02 AWB8230-1413GBControlled decelerationNormally, in the event of a power failure or an Emergency-Stop,the motor coasts to a halt without frequency inverter control. Insome applications, however, it is necessary to control the motor’sdeceleration. This function is provided for such cases.To use this function, the power supply for connections R0 <strong>and</strong> T0must be changed.Proceed as follows:X Release the two screws of terminals R0 <strong>and</strong> T0. Removeconnector J51 with the cable from the circuit board (retain theplug).Warning!Before working on the <strong>DF6</strong>, isolate the device from itspower supply. Risk of fatal injury from electrical current.By default, terminals R0 <strong>and</strong> T0 are connected to phases L1 <strong>and</strong> L3through connector J51 (a fig. 144).R0 T0L1L2L3J51R0T0SMPSU–+VWBRDC–DC+L+M3 hJ51Figure 146: Disconnect J51 from terminals R0 <strong>and</strong> T0Figure 144: Default connection of terminals R0 <strong>and</strong> T0SMPS: <strong>DF6</strong> control electronicsFor controlled deceleration to work, you must connect terminalsR0 <strong>and</strong> T0 to DC+ <strong>and</strong> DC– (a fig. 145).X Connect a cable to terminal R0, which is long enough to reachterminal DC+ (do not connect yet).X Connect a cable to terminal T0, which is long enough to reachterminal DC– (do not connect yet).X Remove the ferrite rings from the connector cable (J51) <strong>and</strong>guide the new cable through the ferrite rings.L1L2L3J51R0T0SMPSU–V M+ W 3 hBRDC–DC+L+T0R0Figure 147: Remove the ferrite rings.Figure 145: Connecting terminals R0 <strong>and</strong> T0 to DC+ <strong>and</strong> DC–SMPS: <strong>DF6</strong> control electronicsX Twist the two cables with each other.X Connect terminal R0 to DC+ <strong>and</strong> terminal T0 to DC–.With this wiring arrangement, the motor can feed the frequencyinverter’s control electronics when the power supply is switchedoff.140
