DIFFERENCES BETWEEN THE G201X AND G201 The G201X is 100% backwards compatible with the G201 and G210. It has several new features and performance enhancements: 1.) 2.) 3.) 4.) 5.) 6.) 7.) 8.) STEP and DIRECTION is +3.3VDC and +5VDC compatible at 2.
POWER SUPPLY HOOKUP TERMINAL 1 Power Ground Connect the power supply ground to term.1 TERMINAL 2 Power (+) Connect the power supply “+” to this terminal The power supply voltage must be between 18 VDC and 80 VDC. The maximum power supply current required is 67% of the motor’s rated phase current. An unregulated power supply may be used as long as the voltage stays between the limits; keep the ripple voltage to 10% or less for best results.
DISABLE PIN TERMINAL 7 Disable This terminal will force the winding currents to zero when shorted to TERMINAL 12. Shorting this input to ground (term. 7 to 12) forces winding currents to zero and stops all output switching activity. The G201X will continue totalizing step and direction inputs if any are sent. The power supply current drops to less than 15mA.
HEATSINKING The G201X needs heatsinking for current settings greater than 3 amps. The case temperature (measured on the bottom plate) should not exceed 70 degrees C, and for best life should be kept to 50 degrees or less. Use heatsink compound between the G201X and the heatsink. CAUTION! Current settings above 3 Amps without a heatsink will result in damage to the G201X. The drive must be heatsinked to a piece of aluminum, preferably with fins and a fan to increase heat dissipation and surface area.
OPTION SET SWITCHES
G210X ADJUSTMENTS This section applies only if you purchased a G210X or have installed a G901X step pulse multiplier. A G201X without a step pulse multiplier has a fixed 10 microstep resolution. ADJUSTING MICROSTEP RESOLUTION The G210X has an onboard step pulse multiplier called the G901X that allows the drive to operate in full step, half step, 5 microstep and 10 microstep modes. The G901X uses a 2mm jumper block and two jumpers to set the resolution.
