11-6 FlexPak 3000 DC Drive Software Reference
ANLG IN 1 GAIN ADJ (P.415)
Gain adjustment for
analog input 1
(terminals 50 and 51
on the I/O Expansion
kit). Parameter Range: 0.750 to 2.250
Default Setting: 1.000
Parameter Type: Tunable
OIM Menu Path(s): Input/Output - Analog I/O
Adjust the gain to get full scale values from the A/D converter when the maximum
level of the applied input signal is different than that of the drive.
For example, if ANLG IN 1 SIG TYPE is set to 0-10 V, a 0-8 VDC signal produces 80%
of the drive’s full scale value. To produce the drive’s full scale value using the
0-8VDC signal, change
ANLG IN 1 GAIN ADJ to 1.250 (8.0V x 1.25 = 10.0V). Gain
values less than 1.000 decrease the resolution of the analog input.
Adjust the zero point ( ANLG IN 1 ZERO ADJ (P.414)) before setting gain.
ANLG IN 1 SIG TYPE (P.413)
Selects the type of
signal that the drive
will expect to be
connected to analog
input 1 (terminals 50
and 51 on the I/O
Expansion kit). Parameter Range: 0– 10 V
+/–10 V
4-20 mA
10-50 mA
Default Setting: +/–10 V
Parameter Type: Configurable
OIM Menu Path(s): Input/Output - Analog I/O
This setting must match the setting of I/O Expansion kit jumpers J11 and J12.
If the input drops below the selected value, the drive uses the low point of the range
(for example, 0 V or 4mA).
ANLG IN 1 ZERO ADJ (P.414)
Adjusts the zero point
of analog input 1
(terminals 50 and 51
on the I/O Expansion
kit) to remove any
offset that might exist
on the input. Parameter Range: –200 to 200
Default Setting: 0
Parameter Type: Tunable
OIM Menu Path(s): Input/Output - Analog I/O
To adjust the zero point, make small changes to this parameter until ANLG IN 1 is
zero when the signal at terminals 50 and 51 is at its zero (0V, 4mA, or 10mA).
