Our stepper motor drivers for easy installation with WinPC-NC or other controllers

The Step1S stepper motor driver card is a low-cost 2-phase driver output stage for a single stepper motor axis with up to 3A. It is equally suitable for retrofitting existing 3-axis stepper motor cards with a 4th axis as well as for the realisation of completely new systems.The Step3S and Step3S HT stepper motor card can be extended by a 4th axis by plugging in the Step1S extension card without any wiring effort. The necessary mounting material is included in the scope of delivery. The step resolution and current settings for the 4th axis are made on the Step3S card.  The Step1S card can also be used for a double motor of the X- or Y-axis. For this purpose, the corresponding signal adapter-2X or signal adapter-2Y can be ordered directly.

For the direct control of stepper motors, we offer our proven Step3S board, which has been further developed many times. With the Step3S card, 3 stepper motors can be directly controlled with up to 3A phase current. To extend the function, the Step1S card is available for a fourth axis and the Step3S-IO card for additional inputs and outputs. The Step3S card has been specially designed for use with WinPC-NC, but is also compatible with any other clock and direction interface from other manufacturers.The Step3S is available both individually and in a robust desktop housing.Highlights of the Step3S board:Up to 3 axes controllable, with Step1S expansion card up to 4 axesPhase current adjustable from 1A to 3A in 0.25A steps for each axisStep resolution adjustable in full, half, quarter, eighth and 1/16 steps or 1/2.5 to 1/10 step with sinusoidal microstep for each axisStepper motors can be connected unipolar and bipolarAC or DC operation without external stabilisation, e.g. with toroidal transformer (12-30VAC or 15-42VDC)Current reduction at standstill controllable via software inputReady switch or EMERGENCY STOP goes directly to Enable of the output stages, e.g. for connection of a safety housingConnection terminal for 5 limit and/or reference switches or other signals3 relay outputs (230V-capable) e.g. for drilling spindle and coolant pump, collet chuck/moletteOperating status indication by LEDs and possibility of integrating them in the front of the housingSafety circuit with evaluation of toggle signal to avoid undefined statesPWM signal evaluation and output 0-10V or 0-5V for spindle controlCombined plug-in/screw terminals for easy installation and maintenanceNormal version up to 50°C ambient temperature and special HT version up to 70°CMotor phase short-circuit and temperature monitoringDetailed operating instructions with all necessary technical detailsAdjustable ramp-up timeDimensions 130 x 150 x 52 mmThe Step3S board is available in two versions:Step3S for ambient temperature up to 50°CStep3S HT for ambient temperature up to 70°CA 25-pin cable for direct connection to the controller is included in the delivery.
