Figure 6.2-11: Output Frequency Supervision
3.10 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 (3.11) this function generates a
warning message via the digital output DO1, via a relay output RO1 or RO2 depending on
the setting of parameters 12.1—12.6.
3.11 Torque limit supervision value
The calculated torque value to be supervised by parameter 3.10
3.12 Reference limit supervision function
0 = No supervision
1 = Low limit supervision
2 = High limit supervision
If the reference value goes under/over the set limit (3.13) this function generates a
warning message via the digital output DO1 or via a relay output RO1 or RO2 depending
on the settings of parameters 12.1—12.6. The supervised reference is the currently active
reference. It can be source A or B reference, depending on the DIB6 input, or the panel
reference if the panel is the active control source.
3.13 Reference limit supervision value
The frequency value to be supervised by the parameter 3.12.
3.14 Extern. brake Off-delay
3.15 Extern. brake On-delay
With these parameters the timing of external brake can be linked to the Start and Stop
control signals, see figure 6.2-12.
The brake control signal can be programmed via the digital output DO1 or via one of relay
outputs RO1 and RO2, see parameters 12.1—12.6.
