Epsilon Eb and EN Drives Reference Manual
Analog Zero Offset
This parameter is used to null any voltage present at the drive when a zero velocity or torque
command is provided by a controller. The amount of offset can be measured by the Analog
Input parameter when a zero velocity or torque command is supplied.
Analog Input
The analog voltage signal that is received on pins 14 and 15 of the Command Connector and
is used to generate the Analog Velocity Command or the Analog Torque Command
depending on the Actual Operating Mode.
For example:
+10 VDC = Maximum motor CW velocity or maximum CW torque.
-10 VDC = Maximum motor CCW velocity or maximum CCW torque.
Analog Outputs Group
Source
Select the signal that you wish to use as the source for Analog Output Channel #1 and Channel
#2. There are five options: Velocity Feedback, Velocity Command, Torque Feedback, Torque
Command and Following Error. The scaling and offset are affected by the source parameter
selected. The units of the scaling and offset are adjusted according to the source parameter.
Offset and Scale
Each analog diagnostic output channel includes a programmable Analog Output Offset and
an Analog Output Scale. These features allows you to “zoom in” to a desired range effectively
increasing the resolution. The units for both of these parameters is dependent upon the Analog
Output Source selection.
Feedback
This is a display of the real time status of the two analog outputs in volts. It is only available
when you are online.
