-Kreutz-4 Rev3.0N (K-4) is a Bipolar, Chopper current control, 4 axes set.
-K-4 accepts 4 or 8 wires motors (and 6 wires motors leaving one wire disconnected on each phase)
-48 Volt Maximum power supply voltage, 15 Volt minimum (Each power board automatically disables when the motor power supply voltage goes over or under the limits).
-5 amperes peak phase current per axis (2 Amps minimum). Individually adjustable by potentiometers and test points.
-The low voltage power supply (+12 Volt) is also monitored to be between 16 Volt and 8.5 volts, otherwise the boards get disabled.
-Idle current reduction (50%) after 1 second inactivity independently for each axis.
-Over current and over temperature protection.
-K-4 can be used on the following modes: Full Step, 1/2, 1/4, 1/8, 1/16, 1/10, 1/5.
-Automatic torque compensation.
-Reference waveform "morphing".
-Firmware Upgrade capability built in.
-External Output connector for interfacing the rest of the LPT port pins.
-Charge-Pump (watch dog) circuit disables the outputs if the 12 KHz signal is not received from the software, protecting against Software "freezes" and LPT cable disconnections.
-4.3 volt brownout protection by resetting the micro-controllers.
-Opto-isolated Inputs and Outputs (except External Output interface signals). RF isolated Step-direction signals up to 2500 volts
-Basic set includes 5 boards (PC interface board with B.O.B. functionality, and 4 power boards).
-3.3 volt or 5 volt PC interface (jumper selectable)
-"Torque Loss" LED, shows you when the motor current can not follow the reference, indicating Torque Loss at the corresponding speed or speed range.
-Firmware Ready LED (for each axis), Service/Adjustment blinking LED.
-Axis Disabled LED (for each axis)
-Current reduction LED (for each axis)
-PC power LED
-Charge Pump OK LED
-E-Stop LED
-Low Voltage Power LED (on every Power board)
-Maximum Step rate: 100 Khz
-Minimum Step and Direction pulse width = 2 uSec @ 100 Khz.
-Step and direction signals are Active "High"-
-Active average current compensation for variable PWM duty cycle.
Works with step-direction software.
RoHS compliant.
Individual or Simultaneous control of all axes.
Power On reset.
On board 5 volt voltage regulation (for each individual board)
PC +5Volts taken from the PC's USB port using a standard USB cable (using USB-B connector on the interface board).
Heat-sinks are not included. Dimensions for a suggested heat-sink will be shown on the documentation..
