FF ON OFF OFF ON OFF OFF OFF OFF OFF OFF OFF 5 2 Current Settings For a given motor higher driver current will make the motor to output more torque but at the same time causes more heating in the motor and driver Therefore output current is generally set to be such that the motor will not overheat for long time operation Since parallel and serial connections of motor coils will significantly change resulting inductance and resistance it is therefore important to set driver output current depending on motor phase current motor leads and connection methods Phase current rating supplied by motor manufacturer is important in selecting driver s current however the selection also depends on leads and connections The latter four bits SW5 6 7 8 of the DIP switch are used to set the dynamic current Select a setting closest to your motor s required current 5 2 1 Dynamic Current Setting 2MA2282 Microstepping Driver Manual V1 0 ECG SA VEBA SE ON OFF ON ON ON OFF ON ON ON OFF OFF OFF OFF OFF ON OFF ON OFF OFF ON ON ON OFF OFF ON OFF ON ON ON OFF ON ON ON Notes Due to motor inductance the actual current in the coil may be smaller than the dynamic current setting particularly under high speed condition 5 2 2 Standstill Current Setting The 2MA2282 has automatic idle current reduction function The current automatically be red
