AR-BS1010ERS series RS232 Dual 1.0 Amp Stepper Motor Controller (not current regulating)
The AR-BS1010ERS is a complete RS232 controlled Unipolar/Bipolar dual stepper motor controller system. When configured with its preprogrammed GenStepper firmware, it includes the capability of driving one or two stepper motors using a single RS232 connection, each of which being either unipolar (4-pole) or bipolar (2 pole). Please note that this is a non-current-regulating controller. This means that you must supply the correct voltage from your power supply to attain the desired current in the coils.
The board is specified as allowing up to 1.0 amps per motor winding when properly cooled, with 6.5 to 15 volt motors supported when in single power supply mode. It also supports a dual power supply feature, wherein the motors use a separate supply from the logic circuits; in this mode, up to a 34 volt power supply may be used for the motors.
The two connector options (L and T) control how you connect to the board. The 'L' option specifies use of latching Amp MTA-100 connectors, while 'T' option specifies use of screw-terminal connectors. The screw-terminal is suggested for anyone who is just doing experiments or is connecting to just one or two motors. The MTA-100 connector is recommended for any production system, since the MTA-100 is vibration resistant, and is easier to use in a production environment.
The board has ESD protection on most of the TTL inputs (except for the RST line). Note that the protection is only active when the board is connected to a properly grounded power supply, such that the GND connection on the board power connector goes to true earth ground.
If your signal sources for the TTL inputs need to be optically isolated (such as signals whose voltage range is in the range of 5 to 24 volts), you may elect to use our AR-OPTOISO4CHAN product to act as an input buffer.
The firmware options describe the "personality" of the board. You can reprogram the board with either of these options at any time using the supplied firmware update tool. If you like, you may use the cart comments field to request a particular firmware (remember: the GenStepper firmware is installed by default, so you only need to do this if you would prefer the NCRouter firmware to be preinstalled on your board.)
- GenStepper (click to see the manual) allows for simultaneous independent asynchronous motion between the two motors. This is normally the firmware preprogrammed onto the board at the time of your order.
- NCRouter (click to see the manual) allows for pen-plotter-like control, wherein perfect rate scaling is automatically performed between the motors in order to generate the equivalent of straight-line motion if a pen plotter were to be attached.
