I/O profile

The run command is simply obtained by bit 0 of the control word.

 

 

 

Reference 1 configuration

Network card

Reference 1 comes from Modbus.

 

 

 

Reference 1B configuration

Analog input 1 on the terminals

Reference 1B comes from input AI1 on the terminals.

 

 

 

Reference switching

Input LI5

Input LI5 switches the reference (1 ↔1B).

 

 

 

Command 1 configuration

Network card

Command 1 comes from Modbus.

 

 

 

Command 2 configuration

Terminals

Command 2 comes from the terminals.

 

 

 

Command switching

Input LI5

Input LI5 switches the command.

 

 

 

Note: Reference 1B is directly connected to the drive reference limit. If switching is performed, the functions that affect the reference (summing, PID, etc) are inhibited.
