7.2 Output Current Configurations
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.
7.2.1 Dynamic Current Configurations
Peak Current RMS Current SW1 SW2 SW3
2.40A(default) 1.70A ON ON ON
3.08A 2.18A OFF ON ON
3.77A 2.67A ON OFF ON
4.45A 3.15A OFF OFF ON
5.14A 3.64A ON ON OFF
5.83A 4.12A OFF ON OFF
6.52A 4.61A ON OFF OFF
7.20A 5.09A OFF OFF OFF
Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting,
particularly under high speed condition. Default means can be set by Leadshine ProTuner
7.2.2 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.
7.3 Control Mode Configurations
DIP switch SW9 is used to configure the control mode. Factory setting is single pulse (step & direction, or pulse &
direction) control. Setting to ON to change the control model to double pulse (CW/CCW) control type.
