Actual signals and parameters 165
4 = AI2/JOYST – Defines analog input 2 (AI2), configured for joystick operation, as the
reference source.
• See above (AI1/JOYST) description.
5 = DI3U,4D(R) – Defines digital inputs as the speed reference source (motor
potentiometer control).
• Digital input DI3 increases the speed (the U stands for “up”).
• Digital input DI4 decreases the speed (the D stands for “down”).
• Stop command resets the reference to zero (the R stands for “reset”).
• Parameter 2205 ACCELER TIME 2 controls the reference signal’s rate of
change.
6 = DI3U,4D – Same as above (DI3U,4D(R)), except:
• A Stop command does not reset the reference to zero. The reference is stored.
• When the drive restarts, the motor ramps up (at the selected acceleration rate) to
the stored reference.
8 = COMM – Defines the fieldbus as the reference source.
9 = COMM+AI1 – Defines a fieldbus and analog input 1 (AI1) combination as the
reference source. See Analog Input Reference Correction below.
10 = COMM*AI1 – Defines a fieldbus and analog input 1 (AI1) combination as the
reference source. See Analog Input Reference Correction below.
11 = DI3U, 4D(RNC) – Same as DI3U,4D(R) above, except that:
• Changing the control source (EXT1 TO EXT2, EXT2 TO EXT1, LOC TO REM)
does not copy the reference.
12 = DI3U,4D(NC) – Same as DI3U,4D above, except that:
• Changing the control source (EXT1 TO EXT2, EXT2 TO EXT1, LOC TO REM)
does not copy the reference.
14 = AI1+AI2 – Defines an analog input 1 (AI1) and analog input 2 (AI2) combination
as the reference source. See Analog Input Reference Correction below.
15 = AI1*AI2 – Defines an analog input 1 (AI1) and analog input 2 (AI2) combination
as the reference source. See Analog Input Reference Correction below.
16 = AI1-AI2 – Defines an analog input 1 (AI1) and analog input 2 (AI2) combination
as the reference source. See Analog Input Reference Correction below.
17 = AI1/AI2 – Defines an analog input 1 (AI1) and analog input 2 (AI2) combination
as the reference source. See Analog Input Reference Correction below.
