CNC 3 Axis Controller Board For Mach3 KCAM4 EMC2 - TB6560 St by Bombay Electronics

Specifications:
1. For toshiba TB6560AHQ chip - High power, maximum 3.5A drive current chipset
2. 1-1/16 microstep setting - Higher accuracy and smoother operation than standard 1, 1/2 step
3. Adjustable drive current settings for each axis - 25%,50%,75%,100% of full current can be set for different stepper motors
4. Overload, over-current and over-temperature safety - Full protection for your computer and peripheral equipment
5· On board current switching - Power output can be set according to specific user requirement
6· Full closed-type optical isolation to protect the user's computer and equipment
7· Relay spindle interface - Outputs Max. 36V 7.5A for spindle motors or coolant pump (only one device can be powered by this output!)
8· 4 channel inputs interface- Can be used for XYZ limit and emergency stop
9· Professional design - Two stage signal processing with super anti-jamming
10· Bipolar constant current chopper drive with non-resonant region - Controls motors smoothly through range without creep effect
11· Four control inputs (divided into pairs of knives) - Allows setting of limit and emergency stop
12· Universal architecture - Supports most parallel software MACH3, KCAM4, EMC2 etc!

Package included:1x TB6560 mould1 x DB25 parallel cable 
Attention:Power supply DC 12-36V (not included)*Voltage Selection:12-16V DC power supply for Nema 17 stepper motors16-24V DC power supply for Nema 23 stepper motors24-36V DC power supply for Nema 34 stepper motors(High voltage will burn up the chips or stepper motors!!!)*Ampertage Selection:Output current of the power supply can be calculated by the following expressions:Output current = Rated current of your stepper motors * quantity + 2A(For example, if you want to drive 3 * 3A Nema 23 stepper motors, theoretically 24V 11A DC power supply is recommended, but higher power such as 24V 15A also will be good.If you are not sure about the selection of power supply, please feel free to contact us for help)The power output of 12V shall be applied to the radiator fan of 12VDriver output compatible with 2 or 4 phase, 4,6 or 8 lead stepper motors, 3A max.Suitable for unipolar or bipolar stepper motors.Voltage regulated spindle speed controlled by parallel interface as function of supply voltage. Specifications:Electrical properties (ambient temperature Tj = 25 pm)Input Power12 - 36V DC power supply Stepper motor drive current3A (peak value 3.5A)/axis Drive type Double-pole constant flow PWM actuation outputCompatible Stepper motors2/4 Phase, 4/6/8 leads stepper motors within 3.5A *Simple solutions if the driver does not work properly:Please double check the software settings according to the Fig.5 and Fig.6Please conform the parallel cable has been pluged tightlyPlease turn off the power supply before changing dip settingsPlease use stable high quality DC power supply for this driverProblems in Mach3 using, Please refer to the Mach 3 User Manual
