Driver functional capabilities
• Operation with any LPT CNC program (STEP/DIR – Mach, TurboCNC
etc.)
• Usage of one supplied voltage for supplying all the scheme, system of
module softstarter.
• Simultaneous control of 4 stepper motors – any bipolar and unipolar
stepper motors (4,6 or 8 outputs) FL57 and others type. We strongly
recommend to use the module with Purelogic R&D stepper motors.
• 4 identical stepper motor drivers (microstep 1:2, 1:8, 1:16, mode
AUTOSLEEP)
Current adjustment in coils of every stepper motor. Fixed PWN
frequency 20 kHz for current control in stepper motor coils.
• AUTO-SLEEP mode automatically reduces current in stepper motor
coils and reduces acoustic noise when in standstill.
• Coil short-circuit module protection, wrong stepper motor connection
protection , polarity reversal supply voltage protection
• Opto-isolation of module and LPT PC port. Current buffering of all
controlling pins of LPT port.
• Control of 2 high current relays 7А/220V and 2 opto-outputs for
commutation of additional machine equipment (spindle, coolant pump
or electric fan).
• Inbuilt regulated timer (time and relay operation duration is
regulated) for commutation of a coolant pump.
• Operation support of frequency converter (regulation of spindle
rotation, PWN converter>voltage), from MACH.
• Control of 5 external sensors state (limit switches) All the inputs are
optoisolated.
• Convenient dismountable clip connectors to step motor, power source
and relay loads.
