For a given stepper motor, as normal setting the output current to 1.4 times of motor phase current, will make it
output larger torque, but at the same time cause more heating for both the motor and drive. Therefore, it is
suggested to set a output current
(peak of sinusoidal) to no more than 1.2 times the stepper motor’s
(for 4-lead
motor) phase current to prevent overheating .
The SW1, SW2 and SW3
are used to set the dynamic current. Select a setting closest to your motor’s required curr
ent.
When they are set to
ON, ON, ON,
the output current can be set by Leadshine ProTuner.

7.2 Micro Step Configuration (SW4-6)
Each EM415S has 8 micro step settings which can be configured through DIP switch SW4, SW5, SW6. See the
following table for detail. When they are set to
ON, ON, ON
, the microstep can be set via Leadshine ProTuner.

7.3 Pulse Mode Configuration (SW7)
DIP switch SW7 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.
7.4 Self-Test Configuration (SW8)
For test and system diagnosis purpose, EM442S is featured with Self-Test. Anytime DIP switch SW8 is switched to ON
position, the drive will automatically rotate the driven stepper motor back and forth for one round in each direction.
Set this switch position to OFF for normal operation.
