Table 7- 43 Parameterizing the monitoring functions
Parameter
Description
No-load monitoring
P2179
Current limit for no-load detection
If the converter current is below this value, the message "no load" is output.
P2180
Delay time for the "no load" message
Blocking protection
P2177
Delay time for the "motor locked" message
Stall protection
P2178
Delay time for the "motor stalled" message
P1745
Deviation of the setpoint from the actual value of the motor flux as of which the
"motor stalled" message is generated
This parameter is only evaluated as part of encoderless vector control.
Speed-dependent torque monitoring
P2181
Load monitoring, response
Setting the response when evaluating the load monitoring.
0: Load monitoring disabled
>0: Load monitoring enabled
P2182
Load monitoring, speed threshold 1
P2183
Load monitoring, speed threshold 2
P2184
Load monitoring, speed threshold 3
P2185
Load monitoring torque threshold 1, upper
P2186
Load monitoring torque threshold 1, lower
P2187
Load monitoring torque threshold 2, upper
P2188
Load monitoring torque threshold 2, lower
P2189
Load monitoring torque threshold 3, upper
P2190
Load monitoring torque threshold 3, lower
P2192
Load monitoring, delay time
Delay time for the message "Leave torque monitoring tolerance band"
