*) High current range available as new additional range with TMCM-1021 hardware revision V1.4 – not with
hardware revision V1.2. High current range settings not recommended for PANdrives PD28-1-1021 and PD28-
3-1021 as the higher current settings will significantly exceed rated motor current of 0.67A RMS.
