Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
Idle-Current
SW4 determines whether current-reduction is performed when there is no pulse applied to 3DM2283..
OFF
Motor current reduces automatically when
SW4
there is no pulse applied to 3DM2283.

Auto-Configuration
Switch SW4 two times in two seconds will activate parameter Auto-configuration for 3DM2283's current loop. That is, OFF-ON-OFF or
ON-OFF-ON. During Auto-configuration, motor parameters are identified and 3DM2283's current loop parameters are calculated
automatically. The motor shaft will vibrate a little during the process of Auto-configuration which takes about 1 to 3 seconds.
