ANLG IN 1 GAIN ADJ (P.415)
Only available if the I/O Expansion kit is installed.
Gain adjustment for analog input 1 (terminals 50 and 51 on the I/O Expansion board).
Parameter Range: 0.750 to 2.250
Default Setting: 1.000
Parameter Type: Tuneable
OIM Menu Path(s): Input/Output - Analog I/O
Refer also to Parameters: ANLG IN 1 (P.492), ANLG IN 1 SIG TYPE (P.413)
ANLG IN 1 ZERO ADJ (P.414)
Adjusting the gain allows full scale results for input signals that are less than the drive's full scale value.
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 0-8 VDC signal, change ANLG IN 1 GAIN
ADJ to 1.250 (8.0V x 1.25 = 10.0 V). Note that gain values less than 1.000 decrease the resolution of
the analog input.

Only available if the I/O Expansion Kit is installed.
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 board). The value of this parameter must match the setting of jumpers J11 and
J12 on the I/O Expansion board. See ANLG IN 1 GAIN ADJ for block diagram.
Parameter Range: 0-10 V, +/-10 V, 4-20 mA, 10-50 mA
Default Setting: +/-10 V
Parameter Type: Configurable

ANLG IN 1 ZERO ADJ (P.414)
Only available if the I/O Expansion kit is installed.
Adjusts the zero point of analog input 1 (terminals 50 and 51 on the I/O Expansion board) to remove any
offset that might exist on the input.
Parameter Range: -200 to 200
Default Setting: 0
Parameter Type: Tuneable
OIM Menu Path(s): Input/Output - Analog I/O
Refer also to Parameters: ANLG IN 1 (P.492), ANLG IN 1 GAIN ADJ (P.415)
To adjust the zero point, make small changes to this parameter until ANLG IN 1 equals zero when the
signal at terminals 50 and 51 is at its zero value (0 V, 4 mA, or 10 mA).
