P2.1 - Basic settings.
P2.1.1
b
AI reference scale minimum value
ID 144
Minimum value:
0.00 Hz
Maximum value:
RefScaleMax Hz
Default value:
0.00 Hz
Description:
Defines the minimum frequency associated with 0% input from the analog input. Setting AI reference scale minimum value and AI
reference scale maximum value both to zero will cause the analog input to scale to the minimum and maximum frequencies.
P2.1.2
b
AI reference scale maximim value
ID 145
Minimum value:
RefScaleMin Hz
Maximum value:
400.00 Hz
Default value:
0.00 Hz
Description:
Defines the maximum frequency associated with 100% input from the analog input. Setting AI reference scale minimum value and AI
reference scale maximum value both to zero will cause the analog input to scale to the minimum and maximum frequencies.

ab
IO terminal Start/Stop logic
ID 143
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Forward - reverse: maintained input on start signal 1 to run forward and a maintained signal on start signal 2 for reverse.
1 = Start - reverse: maintained input on start signal 1 to run and maintain start signal 2 Open for forward, Close for reverse.
2 = Start - enable: maintained input on start signal 1 to run forward and a maintained signal on start signal 2 to enable the drive to run.
3 = Start pulse - stop pulse: used for three-wire operation, start signal 1 uses a normally open start and start signal 2 uses a normally
closed stop.
Description:
Defines the functionality for start signal 1 and start signal 2. By default, start signal 1 is DI1 and start signal 2 is DI2.
0 =
P3.2: IO terminal start signal 1 = start forward - P3.3: IO terminal start signal 2 = start reverse. This would be considered
2-wire control with either a contact used on the start FWD or start REV commands. When contacts open, the motor stops.
