4.1.3. Two axes system Enclosure view

Two-axis controller model consists of two controller boards in a metal case. Case dimensions are 124 x 45 x 106 mm.

Front panel contains power supply connector, USB type-B connector, USB cascade connector, and power LED. The front panel also contains status LED, left and right limit switch LED, left and right movement buttons for each of the two controller boards of the two-axis system.

Rear panel contains stage connector for each of the two controller boards, supplementary two-axis system connector, and joystick connector.

Left side panel contains two Ethernet ports.

The USB type-A cascade connector and Ethernet connector is used to connect several two-axis cases in line terminated with either one-axis or two-axis controller. This way a required number of axes can be connected to the computer with a single cable. Connectors Stage connector

A female DSub 15-pin connector for stage is mounted on the controller board.

Pins functionality:

  1. Not phase B of SM or DC- of the motor
  2. Phase B of SM or DC+ of the motor or phase B on BLDC motor
  3. Not phase A of SM or DC- of the motor or phase C on BLDC motor
  4. Phase A of SM or DC+ of the motor or phase A on BLDC motor
  5. 5 V output, 500 mA - stabilized output for encoder power supply
  6. ID, one-wire interface for stage identification (only for Standa stages)
  7. Logic GND for limit switches, encoder, etc.
  8. 2nd limit switch
  9. 1st limit switch
  10. Encoder channel A
  11. Encoder channel B
  12. Revolution sensor input
  13. Inverted Encoder channel A
  14. Inverted Encoder channel B
  15. Inverted revolution sensor input


Only firmwares 4.1.0 and older support BLDC.


Outputs 1 & 3 and 2 & 4 must be connected together for proper DC motor function if the nominal current of the motor is higher than 3A.


Plugging in/out the motor to the controller is not recommended while motor windings are under voltage. Power supply connector

One and two-axis controller models use Kycon 4-pin DC power connector (part number KPPX-4P, www.kycon.com).



  1. Power, "-".
  2. Power, "+". 12-48V.
  3. Power, "-".
  4. Power, "+". 12-48V.


Never supply the power to the controller and do not plug it to power connector if you are not confident that your power supply parameters conform to the requirements. Never attempt to plug the power supply to the controller if you are not sure power supply unit and controller connectors are compatible! The acceptable connection parameters are described in Safety instructions.


Hot-swapping or unreliable connection of the power supply connector Kycon may damage the PC and/or the controller. For more details please refer to Safety instructions. System control connectors

Controllers connect via connector USB type-B or Ethernet.

Use verified USB cables only! Damaged or low-quality USB cable may cause improper controller operation, including motor rotation errors and errors of device recognition by PC operating system. Short cables with thick wires and screening are ideal for sustainable connection. Joystick connector

A single-axis or two-axis controller model may contain a 9pin DSub male joystick connector.

  1. AXIS1_BUT_R, right button input, axis 1.
  2. AXIS2_Joy, analog 0-3.3 V joystick input, axis 2.
  3. DGND, common ground.
  4. AXIS2_BUT_R, right button input, axis 2.
  5. DGND, common ground.
  6. AXIS1_Joy, analog 0-3.3 V joystick input input, axis 1.
  7. 3.3 V output.
  8. AXIS1_BUT_L, left button input, axis 1.
  9. AXIS2_BUT_L, left button input, axis 2.


If the connector belongs to a single-axis model, then pins 2, 4, 9 are not used.


Unused pins of the internal connector do not require any additional connection or pullup/pulldown. Simply do not use them.


Analog Joy, Pot inputs are designed to work with LESS THAN 3.3 V voltage. Over-voltage may break all analog controller inputs and lead to the controller or motor failure. Supplementary two-axis system connector

Two-axis controller model contains a HDB-26 female DSub connector.
