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. The motor
will return to its original position when the disable input is released if no step pulses have been sent and the motor has not been
moved more than 2 full steps.
STEP AND DIRECTION INPUTS
TERMINAL 8
Direction
Connect the DIRECTION line to this terminal.
TERMINAL 9
Step
Connect the STEP line to this terminal.
TERMINAL 10
Common
Connect the controller’s +3.3VDC, +5VDC or GND to this terminal.
These inputs are optically isolated from the rest of the drive. Terminal 10 is the common connection for the opto-isolators and
must be connected to the +3.3VDC, +5VDC or GND of your indexer or pulse generator. These inputs are meant to be driven by
3.3V to 5.5V logic capable of sourcing or sinking 2.5mA of current. The minimum logic “0” time is .5uS while the minimum logic
“1” time is 3uS with 3.3V – 5V connected on the COMMON terminal. The minimum logic “0” time is 3uS while the minimum logic
“1” time is 0.5uS when connected to GND on the COMMON terminal. Microstepping occurs on the falling edge of the step input
when COMMON is a positive voltage and on the rising edge when COMMON is connected to GND and on the rising edge when
connected to 3.3V – 5V.
CURRENT SET RESISTOR (OPTIONAL)
TERMINAL 11
Current Set (OPTIONAL)
Connect the current set resistor to this terminal.
TERMINAL 12
Current Set (OPTIONAL)
Connect the other end of the current set resistor to this terminal.
DIP Switches 1, 2, 3, 4, and 5 must be set to ON if an external current set resistor is used.
This input programs the G201X’s current output to the motor windings. The G201X will accommodate motor winding currents
from 0A to 7A when using an external current set resistor. Use the following equation to calculate the resistor value in kilo-ohms:
R (in kilo-ohms) = 47 * I / (7 – I)
Shown are the current set resistor values for motor current in .5A increments.
