q_xAlrm	BOOL	Detected alarm bit. TRUE: Alarm detected FALSE: No alarm detected Refer to detailed description below this table.
q_wAlrmId	WORD	Detected alarm identification. Refer to q_wAlrmId. Range: 0...255

q_xOvldAlrm

Indicates an overload incidence if TRUE. That means, during the measurement process stage of the FB a torque value was calculated higher than i_rDrvTrqMax. The distance run since the start of the movement was memorized and the load has to be brought down to the same position where it was moved from to reset the alarm. The alarm is indicated by a constant horn and a flashing red light 1 s on and off.

If using a load cell the input value of i_rSenIputActl is compared to i_stOVLD.dwLoadNom.

q_xOvldWrn

The calculated torque value of the measurement process stage of the FB is higher than 90% of i_rDrvTrqMax. A advisory is given by the yellow light and the horn by being activated for 1 s on and off. The advisory is reset by a new movement/measurement resulting in a lower torque value than 90% of i_rDrvTrqMax. If using a load cell the input value of i_rSenIputActl is compared to 90% of i_stOVLD.dwLoadNom.

q_wDrvSpdRef

This is the speed reference to the hoist drive. It is mandatory to transfer the target speed by this block to get proper functionality of the torque measurement. See the instantiation example.

q_wStat

Status Bit	Description
0	torque measurement in progress
1	weight detection
2	change of load detected, i_stOVLD.wTrqThres
3	Anti-Tip active, i_stOVLD.wAntiTip
4	overload test time greater than 5 hours
5	calibration done
6...12	not used
13	90% load alert detected
14	overload alarm detected
15	load cell enabled

q_xAlrm

An alarm signal is generated in cases of incorrect parameterization of input values. Refer to the q_wAlrmId table below. In case of an alarm the yellow light and the horn are flashing 1 s on and off.

q_wAlrmId

Identification of the alarm, if q_xAlrm is TRUE.

Bit Position	Description Represented by Bit Position
0	i_stOVLD.wSpdDbnd > i_stOVLD.wMeasFreq
1	i_stOVLD.wAntiTip < 2
2	overload timer greater than 5 hours
