6-4 Programming MN792

Parameter Descriptions
Analog Inputs Five analog input blocks are used to scale and clamp the inputs for terminals A2 through A6.

Analog input 1 is the 0–20mA or 4–20mA input. Analog input 2 is the main speed loop input (without

Accel/Decel ramps). Analog input 3 is Speed setpoint no. 3. Analog input 4 is the negative current clamp; this is

only active if bipolar clamps are enabled; ANIN 5 – Main current limit (or positive current clamp if bipolar clamps

are enabled. ANIN 4 is then the Negative current clamp input).

* ANIN 2 (A3) Notes:
1. ANIN 2 output [493] has two permanent connections:
a. SETUP PARAMETERS:: SPEED LOOP::
SETPOINTS:: RATIO 2 (A3) input and
b. SETUP PARAMETER:: CURRENT LOOP:: I DMD.
ISOLATE switch.
If you do not want ANIN 2 output [493] to be in the
Speed or Current Loops, set RATIO 2 (A3) [7] to zero,
and set I DMD. ISOLATE [119] to DISABLED.
2. ANIN 2 (A3) is a direct input into the speed loop/current
loop and is scanned synchronously with the current
loop (typically every 3.33ms rather than every 7ms).
Therefore ANIN 2 should be used for any signal whose
response is critical.
3. Other tags can be connected to ANIN 2 output [493] for
access to the calibrated final value of ANIN 2.
Diagnostic
connection
Diagnostic connection (tag accessible from the Diagnostic
Menu) allows monitoring of the raw analog input signals
from. within the Diagnostics parameter block.
