6.5.3 Parameters File Selection

As explained before (see Software Setup) one of the following files is

used for most of software parameters configuration:

...\bldc_zerocros08MR32\sources\const_cust_hv.h, definitions for software customizing, for high-voltage (230/115 Vac ) power board

...\bldc_zerocros08MR32\sources\const_cust_evm.h, definitions for software customizing for EVM motor board (12 V low power)

...\bldc_zerocros08MR32\sources\const_cust_lv.h, definitions for

software customizing for low-voltage (12 Vdc) power board

According to hardware used, the designated file (see Table 6-1) must be selected by including:

...\bldc_zerocros08MR32\sources\code_fun.c, program c language functions

NOTE: The following parameter settings will be provided in the selected file. Therefore, it will be referred to as const_cost_x.h in the following sections.

6.5.3.1 Software Customizing to Power Stage

The hardware boards parameters customizing is provided in the const_cust_x.h file.

NOTE: Skip this section, when standard modular motion control development hardware boards are used without any changes. When low-voltage power stage ECLOVACBLDC is configured for 42 V, some const_cust_x.h changes are needed.

For setting, follow the labels MUST_IF_HW_CHANGE_nn in file const_cust_x.h from nn = 1. Detailed description starts here.

An example of software customizing to power stage is shown in

Example of Software Customizing to Hardware.
