Operational Overview
Analog Outputs
The drive has two 8 bit 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 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:
Each channel includes a programmable Analog Output Offset and an Analog Output Scale.
This feature 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.
Analog Output Offset units:
• Velocity Command = RPM
• Velocity Feedback = RPM
• Torque Command = Percent of continuous torque for selected motor
• Torque Feedback = Percent of continuous torque for selected motor
• Following Error = Revs
Analog Output Scale units:
• Velocity Command = RPM/volt
• Velocity Feedback = RPM/volt
• Torque Command = Percent of continuous torque/volt for selected motor
• Torque Feedback = Percent of continuous torque/volt for selected motor
• Following Error = Revs/volts
Channel Output Source Offset Scale
1 Velocity Feedback 0 600 RPM/volt
2 Torque Command 0 30 percent/volt for selected motor
