master) or serial port from an externally powered device. The signals applied to the inputs
cannot exceed 5.5V level required to drive logic common or drive damage will occur.
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 provides a programmable Analog Output Source.
Analog Output Source options are:
• 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
Channel Output Source Offset Scale
1 Velocity Feedback 0 600 RPM/volt
2 Torque Command 0
30 percent/volt for selected
motor
