Extended monitoring functions

7.3.3.1

Description

When the extension is activated, the monitoring functions are extended as follows:
● Speed setpoint monitoring: |n_setp| ≤ p2161
● Speed setpoint monitoring: n_set > 0
● Load monitoring
Description of load monitoring
This function monitors power transmission between the motor and the working machine.
Typical applications include V-belts, flat belts, or chains that loop around the belt pulleys or
cog wheels for drive and outgoing shafts and transfer the peripheral speeds and forces.
Load monitoring can be used here to identify blockages in the working machine and
interruptions to the power transmission.
During load monitoring, the current speed/torque curve is compared with the programmed
speed/torque curve (p2182 to p2190). If the current value is outside the programmed
tolerance bandwidth, a fault or alarm is triggered depending on parameter p2181. The fault
or alarm message can be delayed by means of parameter p2192 to prevent false messages
caused by brief transitional states.
