6.2 Output Current Configurations
The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest
to your motor’s required current. Note: “default” means the parameters can be set by GUI tuning software.

6.2.2 Idle Current Configuration
SW4 is used to set motor idle current percentage. At OFF position it means the standstill current is set to be
50% of the selected output current. At ON position it means standstill current is set to be 90%.
The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse.
