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 .
