Rockwell Automation FlexPak 3000 Digital DC Drive Version 4.3 - Manual (Page 25)

Configuring the Speed Reference 4-5
ANLG AUTO GAIN ADJ
(P.101)
Scales the analog
auto reference signal
after it is conditioned
by the drive
hardware. Parameter Range: 0.750 to 1.250
Default Setting: 1.000
Parameter Type: Tunable
OIM Menu Path(s): Drive Reference - Drive Reference Scaling
Typically, this parameter is set to 1.000.
Example
If ANLG AUTO SIGNAL TYPE (P.100) is set to 0 -10V, a 0 to 8.2VDC signal produces
only 82% of the drive’s full scale value. To produce the drive’s full scale value,
change ANLG AUTO GAIN ADJ to properly scale the signal to 1.22 .
Important: Adjust the zero point ( ANLG AUTO ZERO ADJ (P.102)) before setting the
gain adjust.
ANLG AUTO SIGNAL TYPE
(P.100)
Selects the type of
signal applied to the
drive analog auto
reference input. This
is the signal at
terminals 19 and 20
on the Regulator
board. Parameter Range: 0– 10V
+/–10V
4-20 mA
10-50mA
Default Setting: 0– 10V
Parameter Type: Configurable

Important: Jumpers J10 and J12 must be set for the type of analog auto reference
selected. See the hardware manual for instruction.
ANLG AUTO ZERO ADJ (P.102)
Removes any offset
from the analog auto
reference signal. Parameter Range: –200 to 200
Default Setting: 0
Parameter Type: Tunable
OIM Menu Path(s): Drive Reference - Drive Reference Scaling
If ANALOG AUTO REFERENCE (P.188) is not equal to zero when the analog auto
reference signal is set to its minimum value (for example, 0 volts or 4mA), adjust
ANLG AUTO ZERO ADJ up or down until ANALOG AUTO REFERENCE (P.188) equals zero.
