The TB6560 stepper motor driver is a very basic driver designed to be used with 42,57,86 steppers within 3A and 5V. It can be utilized with 2 or 4-phase motors with 4 or 6 wires, and offers the new Toshiba TB6560AHQ chip with a 6N137 high-speed OptoCoupler – designed to provide high speed without step out.

Although this driver doesn’t necessarily produce a lot of heat, it comes fully equipped with overheating protection, a large heat sink, as well as both over-current and low-voltage protection. These features ensure that this driver will maintain optimal performance, with built-in defences against a variety of typical stepper motor driver problems.

This driver also comes at a very affordable price as the low voltages and current don’t require intense heat dispersion or other cost-adding features. Instead, this driver is basic and provides the precise amount of power necessary for a variety of hobbyist and home-project applications. If you are looking for more powerful Stepper Motor Drivers, consider the DQ860MA, DQ542MA or TB6600, although if you don’t require any more power than the TB6560, then this is the ideal choice thanks to its value/performance rating.

Excitation Mode Settings:

The TB6560 is far simpler than stepper motor drivers like the DQ862MA or DQ542Ma, and only dedicates two DIP switches (S3 and S4) to excitation mode settings. As such, the following table shows how these switches need to be set in order to achieve the desired excitation mode:

Output Current Settings:

The TB6560 stepper motor driver utilises the SPST switches SW1, 2 and 3, as well as the DIP switch S1 to set the output current. When setting these, refer to the following table to set the running current as close to your motor’s required input current.

Stop Current and Decay Settings

The final three DIP switches (S2, S5 and S6) are dedicated to the stop current and decay settings. The S2 switch defines the stop current, and either sets it to 20% or 50%, where ON is 20% and OFF is 50%. The S5 and S6 switches are for setting the decay, and the following chart shows how the switches need to be set in order to achieve variable decay settings:
