1106 REF2 SELECT 0…19 1 19 9
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.
1107 REF2 MIN 0.0…100.0% 0.1% 0.0%
(torque: 0…600%)
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 or speed
– maximum process reference
– nominal torque
1108 REF2 MAX 0.0…100.0% 0.1% 100.0%
(torque: 0…600%)
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 or speed
– maximum process reference
– nominal torque
