Function description
The technology application has been extended by a function for the detection of undervoltage which carries out a clearly defined error response if the voltage falls below a DC-bus voltage parameterised in code C03001. The clearly defined error response is a quick stop by trouble (QSP) and is entered into the logbook as Fallen below UG min threshold. The deceleration time of the quick stop is parameterised in Lenze code C00105 as usual. The function only takes effect if a nonzero value has been entered into Lenze code L-C3001. The value is entered in per cent, and an entry of 50.10 % means that a quick stop will be triggered if there is a voltage of 511 V in the DC bus.
Applications
In the event of a mains failure, this function can prevent the motor from coasting down. Instead, the motor will run down along the quick stop ramp as slowly as possible.
