Not all of the parameters can be directly addressed via this range. This is the reason that in
CAN, an inverter parameter always comprises two parameters from the inverter; these are
the offset specified using parameter p8630[2] and the parameter itself.
● for all parameters < 9999 the following applies:
● for all parameters 9999 < 19999 the following applies:
● for all parameters 19999 < 29999 the following applies:
● for all parameters 29999 < 39999, the following applies:
Selection, index range
Further, no more than 255 indices can be transferred in a CANopen object. This means that
additional CANopen objects must be created for parameters that have more indices. This is
realized using p8630[1]. It is possible to transfer a maximum of 1024 indices.
● P8630[1] = 0: 0 ... 255
● P8630[1] = 1: 256 ... 511
● P8630[1] = 2: 512 ... 767
● P8630[1] = 3: 768 ... 1023
Accessing CANopen objects and inverter parameters
● p8630[0] = 0: only accessing CANopen objects (SDO, PDO, ... )
● p8630[0] = 1: Access to virtual CANopen objects (inverter parameters)
● p8630[0] = 2: not relevant for G120 inverters

– p8630[2] = 0,
– Inverter parameters -> hex + 2000 hex
Example: For parameter p0010, 200A hex follows as object number in the SDO job
– p8630[2] = 1,
– (inverter parameters - 10000) -> hex + 2000 hex
Example: For parameter p11000, 23E8 hex follows as object number in the SDO job
– p8630[2] = 2,
– (inverter parameters - 20000) -> hex + 2000 hex
Example: For parameter r20001, 2001 hex follows as object number in the SDO job
– p8630[2] = 3,
– (inverter parameters - 30000) -> hex + 2000 hex
Example: For parameter p31020, 23FC hex follows as object number in the SDO job
