The technical data of the Slider SFX board are...
• Connection of three 2-phase stepping motors direct on the board
• Optional 4th axis as a plug-in board
• Single supply with AC or DC voltage without external stabilisation, meaning easy
supply with a transformer
• Control signals via 25-pin D-Sub type connector (female), e.g. directly from a PC prin-
ter port (LPT)
• Full-, half-, quarter, 8th- to 16th-step, 2.5th to 10th-step also possible (sinusoidal
micro step)
• Phase current up to 3.0A
• Individual setup of phase current for each axis with DIP switches, additional current
reduction input (reducing current to 50%)
• Protected against short windings and shorts to ground
• Ready switch acts as enable signal directly to power stages and relays, can be used
e.g. on a protection hood
• Three relays (240V~/10A) for switching outputs, e.g. main spindle, coolant pump,
chuck etc., also capable of switching DC current
• LED’s to signal supply voltage and other states, additional connector makes it possible
to integrate LED’s into front plate of housing etc.
• 5 free assignable inputs (N.O. or N.C. contacts), e.g. for limit or reference switches
• Protection circuit with toggle or ready signal to disable motors and relays
• Connector for additional 4th axis
• Standard version for ambient temperatures up to 50°C, special HT version for ambi-
ent temperatures of up to 70°C
• Analogue output 0-5V or 0-10V to drive speed controlled milling/drilling spindles,
interpretation of a PWM signal
• Control of a relay depending on PWM value, threshold level 10%
• Emergency signal, N.C. contact
• Dimensions: 150*130*52mm
1.1 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. A fan
mounted to the side of the board or a case
fan ensures proper cooling. A filter with 30
ppi or higher is required.
The version Slider SFX HT is designed for
ambient temperatures up to 70°C and is
equipped with passive heat sinks on both
top and bottom side. A fan should be
used in a similar way than on the standard
version.
