1104 REF1 MIN
Sets the minimum for external reference 1.
• The minimum analog input signal (as a percent of
the full signal in volts or amps) corresponds to
in Hz/rpm.
MIN
• Parameter 1301
MINIMUM AI
sets the minimum analog input signal.
• These parameters (reference and analog min. and
max. settings) provide scale and offset adjustment
for the reference.
1105 REF1 MAX
Sets the maximum for external reference 1.
• The maximum analog input signal (as a percent of
full the signal in volts or amps) corresponds to
in Hz/rpm.
MAX
• Parameter 1302
MAXIMUM AI
sets the maximum analog input signal.
1106 REF2 SELECT
Selects the signal source for external reference
0...17 – Same as for parameter 1103
