Actual signals and parameters 167
1104
REF1 MIN
0.0 … 500.0 Hz 0.1 Hz 0.0 Hz
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 REF1 MIN in Hz/rpm.
• Parameter 1301 MINIMUM AI1 or 1304 MINIMUM AI2 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
0.0 … 500.0 Hz 0.1 Hz 60.0 Hz
(US)
50.0 Hz
(EU)
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 REF1 MAX in Hz/rpm.
• Parameter 1302 MAXIMUM AI1 or 1305 MAXIMUM AI2 sets the maximum analog
input signal.
1106
REF2 SELECT
0...19 1 2

Selects the signal source for external reference REF2.
0…17 – Same as for parameter 1103 REF1 SELECT.19 = PID1OUT – The reference
is taken from the PID1 output. See Group 40: Process PID set 1 and Group 41:
Process PID set 2.
