6.1.4 Group 3.3: References
6.1.4.1 Frequency reference
The requency reference source is programmable for all control places except PC, which al-
ways takes the reference from the PC tool.
Remote control place (I/O A): The source of frequency reference can be selected with param-
eter P3.3.1.5.
Remote control place (I/O B): The source of frequency reference can be selected with param-
eter P3.3.1.6.
Local control place (Keypad): If the default selection for parameter P3.3.1.7 is used the refer-
ence set with parameter P3.3.1.8 applies.
Remote control place (Fieldbus): The frequency reference comes from fieldbus if the default
value for parameter P3.3.1.10 is kept.

P3.3.1.3 PosFreqRefLimit -320.0 320.0 Hz 320.00 1285
Final frequency reference
limit for positive direction.
P3.3.1.4 NegFreqRefLimit -320.0 320.0 Hz -320.00 1286

be used e.g. to prevent motor
from running in reverse
direction.

Selection of ref source when
control place is I/O A
1 = Preset Frequency 0
2 = Keypad reference
3 = Fieldbus
4 = AI1
5 = AI2
6 = AI1+AI2
7 = PID reference
8 = Motor potentiometer
9 = Max Power
P3.3.1.6 I/O B Ref sel 1 9 9 131
