The controller in a metal case, a uniaxial variant of 3D (model 8SMC4-USB-B8-1).


The controller in a metal case, a uniaxial variant of 3D (model 8SMC4-USB-B9-1).

Single-axis controller model is a controller board in a metal case. Case dimensions are 66 x 46 x 114 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 and synchronization connector.

Connectors

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
3 - Not phase A of SM or - DC of the motor
4 - Phase A of SM or + DC of the motor
5 - 5V / up to 100mA 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 - NC for 8SMC4
14 - NC for 8SMC4
15 - NC for 8SMC4

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, anacapa.kycon.com).

Pinout:
1 - Power, "-".
2 - Power, "+". 12-36V.
3 - Power, "-".
4 - Power, "+". 12-36V.

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.)

Synchronization connector

A single-axis or two-axis controller model may contain a synchronization and magnetic brake 9pin DSub female connector.


Pinout of the connector, front view.

Pinout:
1 - Magnetic brake output, axis 1, +24V.
2 - Synchronization input, axis 2, 3.3V logic.
3 - Synchronization input, axis 1, 3.3V logic.
4 - Unused.
5 - GND, ground pin.
6 - Magnetic brake output, axis 2, +24V.
7 - Synchronization output, axis 2, 3.3V logic.
8 - Synchronization output, axis 1, 3.3V logic.
9 - GND, ground pin.

Note. If the connector belongs to a single-axis model, then pins 2, 6, 7 are not used.

Note. In case magnetic brake control board is not connected, then pins 1 and 6 are not used.

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