Belt Threshold Frequency 1; Belt Threshold Frequency 2 - Siemens MICROMASTER 440 Parameter Manual

Belt threshold frequency 1

CStat: CUT
P-Group: ALARMS
Sets a frequency threshold 1 for comparing actual torque to torque the envelope for belt failure detection.
The frequency torque envelope is defined by 9 parameters - 3 are frequency parameters (P2182 - P2184),
and the other 6 define the low and high torque limits (P2185 - P2190) for each frequency (see diagram
below).
P2189
Upper torque threshold 3
P2190
Lower torque threshold 3
P2187
Upper torque threshold 2
P2188
Lower torque threshold 2
P2185
Upper torque threshold 1
P2186
Lower torque threshold 1
The allowed frequency/torque region is defined by the shaded area. When the torque falls outside the area
shown, a trip or warning occurs (see parameter P2181).

P2182[1] : 2nd. Drive data set (DDS)
P2182[2] : 3rd. Drive data set (DDS)
Note:
- The load torque monitoring function is not active below the frequency defined in P2182 and above the
frequency defined in P2184.
- The current and torque limits of the drive inverter and motor still apply over the complete frequency
range.
- The drive inverter output frequency is defined using Parameter P1080 and P1082. These limits should
be carefully observed for the load torque monitoring frequencies.
