Profile

4.1.2. Controller board 2.3.X version

Dimensions and arrangement

Structurally the controlled is designed as two boards, 46x126,75mm each, rigidly connected to each other. A logic controller and control systems are mounted at the bottom board, a power part is at the top board. A radiator at the power part is available.


Top view on the controller. The view from power part and radiator side.


Front view on the controller. The view from stage cable side.


Rear view on the controller. The view from DIN and USB-b connectors side.


Bottom view on the controller. The view from backplane connectors side.

IMPORTANT. If you are mounting the radiator to the power part by yourself, please make sure that there is no contact between heat-conducting surfaces and conductive elements of the unit. Such contact may damage the power circuit! This warning is applicable only to controllers supplied without body.

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.)

Backplane connector

A female 20-pin double-row connector (PBD-20R) with 2.54mm pitch is mounted on the controller board for backplane connection.


Dimensions and output pins numbers in BPC (BackPlane Connector), connector-side view.

Pin function of CN1:
1 - Power GND 12-48В.
2 - Joy, an analog 0-3 V input used for external joystick connection.
3 - Power GND 12-48В.
4 - Pot, an analog 0-3 V input used for general purpose.
5 - Power GND 12-48В.
6 - A common input/output (or an Enable signal if an external driver is used), 3.3V logic.
7 - Power +12...+48В.
8 - U_LED, A LED Status output displaying controller's operating mode.
9 - Power +12...+48В.
10 - L_LIM, A LED output for left limit switch.
11 - Power+12...+48В.
12 - R_LIM, A LED output for right limit switch.
13 - USB_SEL, selecting USB device in Multi-axis system.
14 - A common input/output EXTGPIO1, 3.3V logic.
15 - USB_D0_N, negative out of USB Slave.
16 - H_USB_D0_N, negative out of USB Master.
17 - USB_D0_P, positive out of USB Slave.
18 - H_USB_D0_P, positive out of USB Master.

Pin function of CN2:
1 - Reserved.
2 - RX, serial port, 3.3V logic.
3 - Reserved.
4 - TX, serial port, 3.3V logic.
5 - Reserved.
6 - A Direction signal for external driver control, 3.3V logic.
7 - Reserved.
8 - A Clock signal for external driver control, 3.3V logic.
9 - Reserved.
10 - Synchronization output, 3.3V logic.
11 - Reserved.
12 - Synchronization input, 3.3V logic.
13 - An output for magnetic brake control, 3.3V logic.
14 - Not used.
15 - BUT_R, an external "Right" button.
16 - 5V output.
17 - BUT_L, an external "Left" button.
18 - Digital GND for 3.3V and 5V.

Note. No additional connection or pull-up to ground/power supply is required for idle pins. Just don't use them.

IMPORTANT. A maximum designed operating voltage for Joy and Pot analog inputs is UP TO 3V. Never supply these inputs with higher voltage, including 3.3V value, otherwise the proper operation of all the analog channels of the controller may get disrupted and the controller itself or the motor may get damaged.

IMPORTANT. The outputs available at the internal connector are not protected. Mounting of any additional buffers or filtering chains is a total responsibility of user or developer who designs a backplane intended to use these lines.

IMPORTANT. While the controller is unpowered, no voltage over 0.3V relative to the DGND pin is allowed on the internal connector. Provision of any additional protection preventing those accidents (if possible) is a total responsibility of user or developer who designs a backplane intended to use these lines.
