Applications

11.6 Application: emergency stop with power failure and/or emergency stop (Servo)

carried out, the drive coasts down once a DC link undervoltage has been identified (OFF2). To implement the OFF3 function (emergency stop), the following parameters need to be set:

p1240 = 5 (activates VDC_min monitoring)

As well as the DC link monitor, which is always active, this activates another variable alarm threshold, which should be set to a value above the undervoltage shutdown threshold of 360 V +/–2% in p1248.

p1248 = Active Line Module <= 570 V, Smart Line Module <= 510 V

(alarm threshold in V). When this threshold is reached, fault 7403 is triggered. This threshold indicates that the set value has been undershot.

p2100.0 = 7403

(Number of the fault for which a response is to be defined.)

p2101.0 = 3 (OFF3) response to the fault entered in p2100.0
