It is divi- ded into different chapters, the contents of which are summarised below: Chapter 1:... -
Page 4: What Is Slider Sfx Used For
LPT printer port of a personal computer with appropriate control software. Slider SFX can be used ideally with the software products PC-NC and WinPC-NC that are also available on our shop. The signals are fully compatible to these control programs. -
Page 5: Versions Of Slider Sfx
Dimensions: 150*130*52mm Versions of Slider SFX The stepper motor driver Slider SFX is available in two versions and with optional 4th axis. The standard version is designed for ambient temperatures up to 50°C and has to be used in housings and machines where this ma- ximum temperature is not exceeded. -

DIP switches. The add-on moduleSliderSFX-4 can be ordered together with the main board or later as a single part including mounting material. It can be easily installed by the user. Page 6 Manual Slider SFX... -
Page 7: Start Of Operation
Please make sure to follow all protective regulations before the first initial operation of the board and before connecting or switching on the supply voltage. On the Slider SFX board all connections are equipped with pluggable cage clamps. All connectors will be described in the following sections. The sketch gives a first overview. All relevant connections and settings are marked in grey. -
Page 8: Base Settings On Delivery
The fan that is mounted on the side of the Slider SFX board can be used on both sides of the board, according to assembly and ventilation in the case. If a case with integrated fan is used, the air stream should pass the 6 drivers (IC’s 1, 2, 5, 7, 12 and 17). -
Page 9: Mounting Dimensions
Mounting dimensions X4 – Power supply The stepper motor board Slider SFX can be supplied with either AC or DC voltage. When using AC power, the lower threshold is 12V~ while the upper threshold is 30V~. For DC power the thresholds are 15V= and 42V=, the polarity is irrelevant. The supply input is pro- tected by a glass fuse (6.3A fast blow). -
Page 10: X10 - Control Signals
Together with our CNC control software PC-NC CNC-Control, WinPCNC and X4Step there are no compatibility problems driving a 3 or 4 axes mechanic. Of course any other software with pulse and direction output signals can be used. Page 10 Manual Slider SFX... -
Page 11: Jp1-Jp8 - Jumper Settings, Signal Assignment
JP1-JP8 – Jumper settings, signal assignment Some pins (8, 9, 14, 16 and 17) on Slider SFX can be used for different functions. Section 2.5 gives an overview about all inputs and their functions. The settings are made with jum- pers, while setting connection pins 1-2 is the standard stetting (except for JP10). -
Page 12: Jp6 - Pin14 Drives Relay 2 Or Pwm Logic
PCNC supports the output of a safety signal (“Q219 Toggle/ Ready”). In other products this is sometimes referred to as “charge pump signal”. If enabled, Slider SFX will enable relays and motors only when a valid toggle signal (minimum frequency of 250 Hz) is recognised. -
Page 13: Jp11 - Start Up Time
Current less motors do have a very small holding toque. If they are in motion, they continue running due to the inertia of the axis. A current less Z-axis may fall down on the table or to the mechanical limit due to its mass. Manual Slider SFX Page 13... -
Page 14: X7 - Inputs For Limit And Reference Switches
Pin 2 2.12 X7 – Inputs for limit and reference switches The stepper motor board Slider SFX has 5 inputs that are forwar- ded to signals on the 25 pin D-Sub type connector. These are ex- actly the signals, which are used as inputs on the PC parallel port. -
Page 15: X3(3/4) - Analogue Output Signal For Spindle Control
All relays can switch up to 10A at max. 240VAC. DC currents can be switched also. 2.14 X3(3/4) – Analogue output signal for spindle control Slider SFX can convert a PWM input signal (min. PWM frequency 200 Hz) to an analogue output signal. Many fre-... -
Page 16: X6, X8, X11 - Motor Connectors
2.15 X6, X8, X11 – Motor connectors Slider SFX is designed for 2-phase stepping motors only. It can be used with both bipolar and unipolar motors. If no datasheet is available to your motors, you have measure which connectors be- long to which winding of the motor. -

Page 19: X13 - Connector For External Led's
2.15 X13 – Connector for external LED’s If Slider SFX is mounted into a case, so that the on board LED’s can not be seen from the outside, it is possible to connect some additional LED’s to connector X13, which then can be mounted into the front plate of the case. -
Page 20: X9/X14 - Extension For 4Th Axis
2.21 X9/X14 – Extension for 4th axis To upgrade Slider SFX to a 4 axes driver, connectors X9 and X14 provides the necessary control signals. The upgrade is done with a small add on board, that includes all com- ponents including the connector for the 4th motor. - Page 21 Manual Slider SFX Page 21...
