1104 EXT REF1 MIN
Sets the minimum frequency reference for external reference 1 in Hz. When analog input signal is at
minimum, external reference 1 equals to
1105 EXT REF1 MAX
Sets the maximum frequency reference for external reference 1 in Hz. When analog input signal is at
maximum, external reference 1 equals to
1106 EXT REF2 SELECT
This parameter selects the signal source for external reference 2. The alternatives are the same as with
external reference 1.
1107 EXT REF2 MIN
Sets the minimum reference in %. When analog input signal is at minimum value external reference 2
equals to
EXT REF
• If the PID Control macro is selected, this parameter sets the minimum process reference.
• If any other macro than PID is selected, this parameter sets the minimum frequency reference. This
value is given as a percentage of the maximum frequency.
1108 EXT REF2 MAX
Sets the maximum reference in %. When analog input signal is at maximum, external reference 2 equals to
2 . See Figure 22.
EXT REF MAX
• If the PID Control macro is selected, this parameter sets the maximum process reference.
• If any other macro than PID Control is selected, this parameter sets the maximum frequency reference.
This value is given as percentage of maximum frequency.
