TC78H670FTG
Step Resolution Select Function
Step resolution is set up. TC78H670FTG has the two modes, Variable Mode and Fixed Mode. These modes are set up by the input state of MODE0-3 pins after releasing standby mode. Variable Mode: Variable mode can be started with Full step resolution and changed step resolution during motor operating Fixed Mode: Fixed mode can be started with the mode user selected and continued it during motor operating MODE3 MODE2 MODE1 MODE0 Mode Function pin input pin input pin input pin input Full step resolution <-> 1/2 step resolution L L L H (2-phase excitation) (1-2-phase excitation) Full step resolution <-> 1/4 step resolution L L H L (2-phase excitation) (W1-2-phase excitation) Full step resolution <-> 1/8 step resolution L L H H (2-phase excitation) (2W1-2-phase excitation) Full step resolution <-> 1/16 step resolution L H L L Variable Mode (2-phase excitation) (4W1-2-phase excitation) Full step resolution <-> 1/32 step resolution L H L H (2-phase excitation) (8W1-2-phase excitation) Full step resolution <-> 1/64 step resolution L H H L (2-phase excitation) (16W1-2-phase excitation) Full step resolution <-> 1/128 step resolution L H H H (2-phase excitation) (32W1-2-phase excitation) H L L L Full step resolution (2-phase excitation) H L L H 1/2 step resolution (1-2-phase excitation) H L H L 1/4 step resolution (W1-2-phase excitation) H L H H 1/8 step resolution (2W1-2-phase excitation) Fixed Mode H H L L 1/16 step resolution (4W1-2-phase excitation) H H L H 1/32 step resolution (8W1-2-phase excitation) H H H L 1/64 step resolution (16W1-2-phase excitation) H H H H 1/128 step resolution (32W1-2-phase excitation) 8 2019-11-28
