Figure 33. Frequency/Torque Curve.
The zone that is shaded gray shows the permissible frequency/torque area. The frequency limit
values 1 to 3 define the areas used to compare the actual torque to the preset torque. Nine
parameters define torque monitoring. Belt Threshold Frequency 1-3 parameters P2182 through
P2184 define the frequency limit values to be set. Upper and Lower Torque Threshold 1-3
parameters P2185 through P2190 limit the tolerance band compared to the present torque curve.
Parameter Settings for Belt Failure Detection without Sensor (Commissioning)
P2182 to P2184, Frequency limit value
The three frequency limit values F1, F2, and F3 determine a reasonable division across the
required torque area. Set the values desired in the manual mode using
and and read and
write down the corresponding torque values via parameter r0031.
Factory setting: 5, 30, 50 Hz.
P2181, Reaction of drive belt failure detection
P2181 sets the desired reaction of drive belt failure detection. Possible settings:
0=Belt failure detection disabled (factory setting).
1=Warn low torque/speed.
2=Warn high torque/speed.
3=Warn high/low torque/speed
4=Trip low torque/speed.
5=Trip high torque/speed.
6=Trip high/low torque/speed
Set P2181 (not to 0) before setting P2185 through P2190.
P2185 through P2190, Torque limit value
Set the torque limit value parameters as follows:
