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
