Table 7. HW ID1 and ID2 function 
 
HW_ID inputs are used to select unique parameter sets for different functions when several inverters with 
identical software are present in the same system (on the same CAN bus). This can be achieved by adding 
jumpers in the cable harness for the different nodes. The HW_ID jumper configuration controls which CAN ID 
and which functionality is used for each position in the system. The HW_ID:s are commonly used to 
differentiate between e.g. left and right traction controller or hydraulic pump controller in a forklift truck. 
CANopen Node ID for each HW ID is defined by the application software. By default the CANopen Node ID 
is HW ID + 5. 
 
NOTE 
For GVI 35 pin version; Digital input 5 and 6 can be used for the same function. For correct HW 
ID with I/O version GVI the K1 pins shall be open for 0 and connected to B+ for 1. 
 
8.5.2.  Protection 
HW ID1 and HW ID2 inputs have a capacitor to B- for ESD protection. The input is protected against 
unintentional connection to B+ and B-. 
 
NOTE 
The HW_ID_GND pins are not protected against short circuit to B+.
