Selects the signal source for external reference
REF
1.
0 =
KEYPAD
– Defines the control panel as the reference source.
1 =
AI
1 – Defines analog input 1 (
AI
1) as the reference source.
2 =
AI
2 – Defines analog input 2 (
AI
2) as the reference source.
3 =
AI
1/
JOYST
– Defines analog input 1 (
AI
1), configured for joystick operation, as the reference source.
• The minimum input signal runs the drive at the maximum reference in the reverse direction. Define the minimum
using parameter 1104.
• The maximum input signal runs the drive at maximum
reference in the forward direction. Define the maximum
using parameter 1105.
• Requires parameter 1003=3 (request).
Warning! Because the low end of the reference range
commands full reverse operation, do not use 0 V as
the lower end of the reference range. Doing so means
that if the control signal is lost (which is a 0 V input)
the result is full reverse operation. Instead, use the
following set-up so that loss of the analog input
triggers a fault, stopping the drive:
• Set parameter 1301
MINIMUM AI
1 (1304
MINIMUM AI
2) at
20% (2 V or 4 mA).
• Set parameter 3021
AI
1
FAULT LIMIT
to a value 5% or
higher.
• Set parameter 3001
AI
<
MIN FUNCTION
to 1 (
FAULT
).

JOYST
– Defines analog input 2 (
AI
2), configured for joystick operation, as the reference source.
• See above (

D
(
R
) – Defines digital inputs as the speed reference source (motor potentiometer control).
• Digital input
DI
3 increases the speed (the
U
stands for “up”).
• Digital input
DI
4 decreases the speed (the
D
stands for “down”).
• A 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 =
DI

D
– Same as above (

• 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.

DI
5 and
DI
6 are the digital inputs used.
8 =
COMM
– Defines the fieldbus as the reference source.
9 =
COMM
+
AI
1 – Defines a fieldbus and analog input 1 (
AI
1) combination as the reference source. See Analog Input
Reference Correction below.
