WARNING!
(*) External power supply.
(**) For current, S1 switch must be ON.
11.3 INCREMENTAL ENCODER
Applications that require more speed or positioning accuracy, a speed feedback of the motor shaft by means of incremental encoder is required.
The connection to the inverter is made through the XC9 connector (DB9) on the EBA function expansion board, or XC9 on EBB, or XC10 on
EBC.
