Troubleshooting Your 8720MC Servo Drive

Parameters 691 and 692 - Analog Input 1 Value and Analog
Input 2 Value

These parameters may be used to display the analog inputs as the
8720MC sees them. The scaling is.00% to 100.00% where 100% = 10
volts. The displayed values include the associated analog offsets,
Parameters 693 and 694.

Troubleshooting SCANport
I/O

Two parameters are available to monitor the SCANport command and
status information exchange, parameters 717 and 718.

Parameter 717 - SCANport Logic Command

A SCANport peripheral gateway device such as an A-B PLC can initiate
drive activity via the SCANport Logic Command word. The structure of
parameter 717 is as follows. The 12 character command messages are
shown in italics.
