Diagnostic Analog Output Test Points - Emerson Epsilon Eb Series Reference Manual

Normally, "All On" for less than one second during power-up. All segments dimly lit when
power is "Off" is normal when an external signal is applied to the encoder inputs (motor or
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.
