RL78/G1F Motor Driver Board GB01
8.5 3-Phase Voltage Detection Filter Switching Circuit
This board integrates a circuit used to switch the filter constant for 3-phase voltage detection. When the
signal level of the corresponding pin is changed, C of the ERC filter is switched, and the filter constant can
thus be changed.
