Start-Up
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
REF1
MIN in Hz.
• 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
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.
• Parameter 1302
MAXIMUM AI1 or 1305 MAXIMUM AI2
sets the maximum analog input signal.
1106 REF2 SELECT
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 Groups 40 and 41.
20, 21 – Same as for parameter 1103
REF1 SELECT.
1107 REF2 MIN
Sets the minimum for external reference 2.
• The minimum analog input signal (in volts or amps) corresponds to REF2 MIN in %.
• Parameter 1301
MINIMUM AI1 or 1304 MINIMUM AI2 sets the minimum analog input signal.
• This parameter sets the minimum frequency reference.
• The value is a percentage of the:
– maximum frequency.
– maximum process reference
1108 REF2 MAX
Sets the maximum for external reference 2.
• The maximum analog input signal (in volts or amps) corresponds to
REF2 MAX in %.
• Parameter 1302
MAXIMUM AI1 or 1305 MAXIMUM AI2 sets the maximum analog input signal.
• This parameter sets the maximum frequency reference.
• The value is a percentage of the:
– maximum frequency.
– maximum process reference
