ANALOG INPUTS
The analog input block is used to scale and clamp the inputs for terminals A2 to A6.
Note:
Terminal ANIN 2 (A3) is p
permanently
connected to SETPOINT 2 (A3) in the SPEED
LOOP function block and to the Current
Demand via I DEMAND ISOLATE (the current demand isolate switch) in the CURRENT
LOOP function block.
To avoid interference with other drive functions when not required: the parameter
RATIO 2 (A3) (Tag 7 in the SPEED LOOP function block) must be set to zero; and the I
DMD. ISOLATE parameter (Tag 119 in the CURRENT LOOP function block) must be set
to DISABLED, i.e. selecting the Speed Loop as shown in the Main Block Diagram.
Because ANIN 2 (A3) is scanned synchronously with the current loop (typically every
3.3/2.6ms, 50/60Hz), it should be used for any signal whose response is critical e.g. a
trim input from an external positioning system or load share.

This parameter is the output diagnostic for terminal A3 (ANIN 2). Note by default 10V =
100%. To obtain a different range, adjust the CALIBRATION, MAX VALUE and MIN
VALUE parameters. Use this parameter to access the calibrated value of ANIN 2 (via an
internal link for example).
