1107 EXT REF2 MIN
Sets the minimum reference in %. When analogue input signal is at minimum
value external reference 2 equals to
• 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 analogue input signal is at maximum,
external reference 2 equals to
• 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.
