184 Parameters31.33 Emergency rampsupervision delayIf parameter 31.32 Emergency ramp supervision is set to 0%,this parameter defines the maximum time an emergency stop(mode Off1 or Off3) is allowed to take. If the motor has notstopped when the time elapses, the drive trips on 73B0Emergency ramp failed, sets bit 8 of 06.17 Drive status word2, and coasts to a stop.If 31.32 is set to a value other than 0%, this parameterdefines a delay between the receipt of the emergency stopcommand and the activation of the supervision. It isrecommended to specify a short delay to allow the speedchange rate to stabilize.0 s0…100 s Maximum ramp-down time, or supervision activation delay. 1 = 1 s31.36 Aux fan faultbybassTemporarily suppresses auxiliary fan faults.Certain drive types (especially those protected to IP55) havean auxiliary fan built into the front cover as standard. If the fanis stuck or disconnected, the control program generates afault (5081 Auxiliary fan broken).If it is necessary to operate the drive without the front cover(for example, during commissioning), this parameter can beactivated to temporarily generate a warning (A582 Auxiliaryfan missing) instead of the fault.Notes:• The parameter must be activated within 2 minutes of drivereboot (either by cycling the power or by parameter 96.08).• The parameter will be in effect until the auxiliary fan isreconnected and detected, or until the next control unitreboot.OffOff Normal operation, Aux fan supervision generates a fault. 0TemporarilybypassedThe auxiliary fan fault is temporarily replaced by a warningindication.The setting will revert automatically to Off.13232 Supervision Configuration of signal supervision functions 1…6.Six values can be chosen to be monitored; a warning or faultis generated whenever predefined limits are exceeded.See also section Signal supervision (page 92).32.01 Supervision status Signal supervision status word.Indicates whether the values monitored by the signalsupervision functions are within or outside their respectivelimits.Note: This word is independent of the drive actions definedby parameters 32.06, 32.16, 32.26, 32.36, 32.46 and 32.56.0000b0000h…FFFFh Signal supervision status word. 1 = 1No. Name/Value Description Def/FbEq16Bit Name Description0 Supervision 1 active 1 = Signal selected by 32.07 is outside its limits.1 Supervision 2 active 1 = Signal selected by 32.17 is outside its limits.2 Supervision 3 active 1 = Signal selected by 32.27 is outside its limits.3 Supervision 4 active 1 = Signal selected by 32.37 is outside its limits.4 Supervision 5 active 1 = Signal selected by 32.47 is outside its limits.5 Supervision 6 active 1 = Signal selected by 32.27 is outside its limits.6…15 Reserved
