4.1.2. One axis system

Single-axis controller model is a controller board in a metal case. Case dimensions are 62 x 44 x 124 mm.
Front panel of the controller contains power supply connector, USB-B data connector, status LED, power LED, left and right limit switch LEDs, left and right movement buttons.
Rear panel contains positioner connector.


Positioner connector

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

Dimensions and numbers of the pins in DSub connector (front view).

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 - 500mA - for 8SMC5, stabilized output for encoder power supply
6 - One-wire interface for positioner identification (for Standa hardware only)
7 - Logic ground 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

Note. Only firmwares 4.1.0 and older support BLDC

Note. 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.

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

Power supply connector. 1 and 2 axes system

One- and two-axis controller models in metal cases use Kycon 4-pin DC power connector (part number KPPX-4P,

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

IMPORTANT. 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.

IMPORTANT. Hot-swapping or unreliable connection of the power supply connector MF-4MRA may damage the PC and/or the controller. For more details please refer to Safety instructions.

Data connector. 1 and 2 axes system

Controllers in metal case connect via USB type-B connector.

USB-A - USB-B cable.

USB type B connector.

Output pin table
Pin # Name Wire color Description
1 VCC Red +5 VDC
2 D- White Data -
3 D+ Green Data +
4 GND Black Ground

Warning. 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.)
