10. Connection of Motor
2L415B driver can drive any 2 phrase / 4 phrase motor with 4, 6 or 8 lines under 1.5A
current. Phrase A of the stepping motor connected between 3 and 4 pins of P2, phrase B
connected between 5 and 6 pins of P2. The detailed connection of 4, 6, 8 lines stepping
motor is listed as below:
11. Matching between driver and motor
This driver can drive any 2 phrase and 4 phrase motor under 1.5A current, in order to get the
most perfect effect, must set the proper supply voltage and current. The supply voltage
determines the speed of the motor, and the current determines the output torque of the motor.

1. Supply voltage setup:
Generally speaking, when the motor runs at high speed, higher voltage makes higher torque
so avoid step-lost. But in the other way, high voltage can lead over-voltage protect or, the
driver will be damaged, furthermore, operate under high voltage, the low speed vibration is
very large, so usually set the voltage to be DC24-36V.
2. Output current setup:
For the same motor, higher current means higher torque, but both the motor and diver’s
radiation are seriously. So the current usually set to be the value of tepid but not heat which
occur in motor’s continuous working status.
(1). 4 and 6 lines motor high speed mode: output current set to be the same, or a little bit less
then the motor’s rate current;
(2). 6 phase motor high torque mode: output current set to be 70% of the motor’s rate
current;
(3). 8 lines motor in series connection: output current set to be 70% of the motor’s rate
current;
(4). 8 lines motor parallel connection: output current set to be 140% of the motor’s rate
current.
Note: Run the motor for 15-30 minutes after setting the current, if the motor’s temperature
rise too high, lower the setting current. If the output torque is inadequate after lower the
current, improve the radiation condition to ensure that the motor and driver not burn hand.
It’s better to let the driver work in breezy environment or fix it in metal board to improve
the radiation.
