Pump control with autochange
3. 10 Output frequency limit 1, supervision value
3. 12 Output frequency limit 2, supervision value
The frequency value to be supervised by the parameter 3. 9 (3. 11).
See figure 6-10.
3. 13 Torque limit, supervision
function
0 = No supervision
1 = Low limit supervision
2 = High limit supervision
If the calculated torque value goes under/over the set limit (3. 14) this function
generates a warning message via the digital output DO1 or via a relay output RO1
or RO2 depending on the settings of the parameters 3. 6—3. 8.
