Code Description
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 amperes) corresponds to
Hz/rpm.
• Parameter 1301
MINIMUM AI
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 amperes) corresponds to
in Hz/rpm.
• Parameter 1302
MAXIMUM AI
the maximum analog input signal.
1106 REF2 SELECT
Selects the signal source for external reference
0...17 – Same as for parameter 1103

1107 REF2 MIN
Sets the minimum for external reference 2.
• The minimum analog input signal (in volts or amperes) corresponds to
• Parameter 1301
MINIMUM AI
• This parameter sets the minimum frequency reference.
• The value is a percentage of the:
– maximum frequency or speed
– maximum process reference
– nominal torque.
1108 REF2 MAX
Sets the maximum for external reference 2.
• The maximum analog input signal (in volts or amperes) corresponds to
• Parameter 1302
MAXIMUM AI
• This parameter sets the maximum frequency reference.
• The value is a percentage of the:
– maximum frequency or speed
– maximum process reference
– nominal torque.
