/* MUST_CHANGE_nn: */
Label for changes which must be set (changed) when adapting
software for a motor
/* MUST_CHANGE_nn_EXPER: */
Label for changes which must be set (changed) when adapting
software for a motor — the setting can be done experimentally
/* MUST_IF_HW_CHANGE_nn */
Label for changes which must be set (changed) when a power
stage board different from high voltage power board is used
/* CAN_CHANGE_nn */
Label for changes which can be set (changed) when adapting
software for a motor, but usually the setting is not needed
/* CAN_CHANGE_nn_EXPER */
Label for changes which can be set (changed) when adapting
software for a motor, but usually the setting is not needed — the
setting can be done experimentally
The other parameters, like motor PWM frequency and current sampling
period can be set in the file const.h. The required steps are marked:
/* CAN_CHANGE_FPWM_n */
Label for definitions which should be modified, when changing
PWM frequency
/* CAN_CHANGE_PERCURSAMP_n */
lLabel for definitions which should be corrected, when changing
current sampling period
Let's follow the next sections, or the labels in the source code to
customize the software.
