Current Settings
For a given motor, higher drive current will make the motor to output more torque, but at the same time causes more
heating in the motor and drive. 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 drive output current depending on motor phase current, motor leads and
connection methods. Phase current rating supplied by motor manufacturer is important in selecting drive current,
however the selection also depends on leads and connections.
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.

Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting,
particularly under high speed condition.
