* 3 x STEP1 3.5A/phase stepper motor drive cards * 1 x STEPBUS connecting cable An economical CNC controller card for 1, 2, 3 or 4 axis control. The M401 has almost all of the features of our M64x series controllers except for the feed-back/closed-loop options and the 5th and 6th axis control but at a lower price. The M401 can be connected to 1, 2, 3 or 4 stepper motor drive cards to control a 1, 2, 3 or 4 axis machine. Despite the simplicity and low price the card has support for connecting jog-buttons and limit-switches to provide full control of a CNC machine. The M401 also has support for attaching an electronic hand-wheel for precise axis control when jogging. The hand-wheel can also be used as a feed-rate override when running programmes. The M401 will control our STEP1 and STEPHP1 stepper motor drive cards or any 3rd party stepper motor drive card or servo-motor drive card which supports the step&direction control standard. The X641SC - stepper converter board is available to simplify connecting to 3rd-party motor drive cards. The M401 Installation manual can be downloaded here.

The card is supplied with EaziCNC 2... our CNC editing and machine control programme. You can download EaziCNC 2 for evaluation here. * 32Mhz RISC processor with user upgradeable firmware in EEPROM * Digital control signals for off-board motor-drives (we can supply cards for up to 65 volts @ 8A/phase if required) * Connections for 6 axis-control buttons (2 per axis), 6 limit-switches/digital-inputs, 'Enter' button and 'Stop' button * Connection for digital hand-wheel for jogging and feed-rate override * 2 12-volt relay drivers for control of spindle and coolant * Optically isolated analogue output for spindle motor speed control * Single DC supply (12-36 volts) required * Full 4-axis motion support including cubic and Bezier splines * Integrated aluminium heat-sink and mounting plate * Compact size. 70x90 mm. mounting area, 45 mm. height inc. heat-sink * Serial/RS232 connection. Does NOT connect to the PC parallel port and does NOT require the installation of some dodgy device driver! Features that this product offers that others often do NOT... * ISO G&M codes - an industry standard so you can use our CAD/CAM or any 3rd party CAD/CAM. * Full simultaneous interpolation of 4-axes. * Axis-following - you can set U to follow X, Y or Z - perfect for parallel drive machines. * Jog-buttons - you would be surprised how useful these are - although maybe not if you tried some of the competition that don't have them? * Electronic hand-wheel for fine positioning and feed-rate override. * Single- and multi-slot spindle sensor inputs for threading/tapping, etc. * Hard-wired safety - a surprising number of parallel-port style controllers have no safety circuit at all! * EaziCNC 2 software - again compare it to the competition. It is also included in the price. We write it ourselves, it is not 3rd party shareware and it is not feature limited. * Vista compatible software and hardware 3.5A/phase stepper motor drive card The STEP1(R4) is a bi-polar stepper motor drive card for motors at up to 45 volts at 3.5Amps/phase. The new revision 4 card has lower power dissipation, an increased voltage range and can drive bigger motors than ever before... typically the current setting for a motor wired for bi-polar use is just 60% of the uni-polar current rating or 40% of the bi-polar current rating. * Bi-polar chopper drive, 12 to 45 Volts, up to 3.5 A/phase * Step rates up to 20,000 steps/sec. * Selectable full- and half- step modes or quarter- and octi- micro-stepping modes (200, 400, 800 and 1600 steps per rev with typical 1.8° motors) * Current settable from 0.25 to 3.5 Amps (16 settings). * Selectable PLL mode for maximum step rates with micro-stepping outputs (peak PLL step-rate is <2Khz) * Digital inputs for Enable, Step-clock and Step-direction. Low 'setup' and 'hold' time requirements for Step-clock and Step-direction (<5us)... the values are internally latched * Compact size. 70x95 mm. mounting area, 45 mm. height inc. heat-sink Torques quoted are for bi-polar drive. Other motors with similar voltages and current requirements will also be compatible. (all content is the responsibility of the poster) |
