Taking SL86S278A as an example, the phase current is 4.2A. If: the stepper driver SL2680 driver current is adjusted to (4.2A * 1.4 =) 5.8A or less. The stepping driver is suitable to be adjusted between 4.5 ~ 5.5A. This connection method is suitable for stepper motor high-speed operation.
2. Series connection method:
1. Taking SL86S278A as an example, the phase current is 4.2A. Connect the current of this stepping driver SL2680 driver to (4.2A / 1.4 =) below 3.0A. The stepping driver can be adjusted to 2.6A.
The two ends of the stepper motor A- and C are connected together and wrapped with insulating tape (that is, the AC end). The two ends of the stepper motor B- and D are connected together and wrapped with insulating tape (that is, the BC end).
2. If the current of SL86S278A stepper driver SL2680C driver is adjusted to (4.2A / 1.4 =) 3.0A or less. The stepping driver can be adjusted to 2.8A. Connect the two ends of the stepping motor A- and C in parallel (that is, the AC end) to the AC end of the driver, and connect the two ends of the stepping motor B- and D in parallel (that is, the BC end) Connect to the BC end of the driver. This connection method is suitable for stepper motor running at low speed.
