10.4 Analog Input
10.4.1 Analog Input
If the drive command source is set to analog, then the analog input to the drive supplies the current or velocity
command to the control loops of the drive.The default analog input screen displays a summary block diagram of
the analog input. You can adjust the analog input settings from this view as follows:
Button or Dialog Box Description Parameter
Offset The offset adds a bias to the analog input com-
mand. This offset is commonly used to remove any
biases that may be present on the analog input sig-
nal.
AIN.OFFSET
Input Voltage The value of the analog input after the offset, dead-
band, and low pass filters.
AIN.VALUE
Scale If the opmode is current mode, then this value is the
amount of current that will be commanded for each
volt on the analog input.
If the opmode is velocity mode, then this value is
the velocity that will be commanded for each volt on
the analog input.
AIN.ISCALE
AIN.VSCALE
AIN.PSCALE
Torque Command The current or velocity command that is sent to the
control loops.
IL.CMD PL.CMDor
VL.CMD
Click the More button to access a detailed view of the analog input. You can adjust additional analog input set-
tings from this view as follows:
Button or Dialog Box Description Parameter
Low Pass Filter The break point frequency for the low pass filter. AIN.CUTOFF
Deadband
The threshold for the deadband. This parameter is
commonly used to reduce noise while the drive is
stationary.
AIN.DEADBAND
Both analog input views provide a link to the encoder emulation output setup; see 8.4.1 Encoder Emulation for
more details on this feature.

10.5 Analog Output
The drive has one analog output. You can either directly control the voltage output or select a different mode to
output different signals. Analog output is configured through the X8 connector; for detailed information this con-
nector, see Connection Diagrams, Analog Output.
Button or Dialog Box Description Parameter
Analog Output Mode
Select which internal signal is output by the
analog output.
AOUT.MODE
Analog Output Value
(user)
Enter the analog output value (when
AOUT.MODE = 0, analog output signal is deter-
mined by the user)
