Diagnostics and Troubleshooting
Diagnostic Analog Output Test Points
The drive has two 8-bit real-time analog outputs which may be
used for diagnostics, monitoring or control purposes. These
outputs are referred to as Channel 1 and Channel 2. They can
be accessed from the Command Connector on the drive or from
the Diagnostics Analog Output Pins located on the front of the
drive.
Each Channel can be programmed to the following sources:
Analog Output Source options
• Velocity Command
• Velocity Feedback
• Torque Command (equates to Torque Command Actual
parameter)
• Torque Feedback
• Following Error
Default Analog Output Source
• Channel 1 = Velocity Feedback
• Channel 2 = Torque Command
The DGNE cable was designed to be used with either an
oscilloscope or a meter. The wires are different lengths to avoid
shorting to each other. However, if signals do get shorted to
GND, the drive will not be damaged because the circuitry is
protected.
Output Source Offset Scale
1 Velocity Feedback 0 600 RPM/volt
2 Torque Command 0
30 percent/volt for
selected motor
