Analog Output
A 0-10 V analog output is provided. The function of this output is
programmable. It can be used for position, velocity or current monitoring.
The intent of this output is to provide a “monitor” type value not a
“control” value, meaning the performance is not intended for the user to
close a high speed position loop around this signal.
The Analog Reference terminal should only be connected when used
with an isolated or differential input. DO NOT CONNECT TO A
GROUNDED POINT EXTERNALLY!

Communications
Serial communication to the actuator is provided through the 8 mm
communication connector on the front of the actuator and also via
terminal connection on J5 under the access cover on 75 mm and 90 mm
models. The serial interface is two wire opto-isolated RS485 network.
The actuator supports the Modbus RTU protocol for access to all drive
parameters (see Modbus Parameter Reference). The Default baud rate
is 19.2k. The default Modbus address is 1.
