Nettet12. okt. 2015 · Rating: (201) On a trip, the pulses are disabled so you are no longer adding energy into the system. The motor will coast down since there is no active braking any more (drive is disabled). The voltage cannot increase since there is no additional energy added to raise it. You only get a rise in voltage on active braking.
