Connectors and Interfaces


Interfaces


DC Bus Input

Input connector for DC bus power. Nominal 48V, but can operate anywhere in between limits defined in JCS Standard Voltages.

Connector

Connector type 1.3mm PCB solder through holes (Up to 16AWG)

Pins Description

Pin Signal Description
+ +VDC DC bus power input
- GNDV DC bus power return

WARNING:

No reverse polarity protection is implemented on the high power connectors.

WARNING:

Motor may act as a generator and energy may be produced at these pins. The source supplying these pins must account for this.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


3 Phase Motor Interface

Connector

Connector type 1.3mm PCB solder through holes (Up to 16AWG)

Pins Description

Pin Signal Description
A A Motor phase A connection
B B Motor phase B connection
C C Motor phase C connection

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


12V Supply Interface

Connector

Connector type Molex PicoClasp 4 Pins
Mating part number 5019390400

Pins Description

picoclasp 4 pin pinout

Pin Signal Description
1 +12V +11V minimum, +13V maximum
2 +12V
3 GND
4 GND

NOTE:

This connection is required. The device does not generate internal 12V from the DC Bus input.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


JCS Network Interface

One network input connector and one network output connector. Interface is galvanically isolated. Power to the isolated side of the network is derived from the host device, eg a joint controller.

NOTE:

If this device is the last in a network chain the output must have the loop back connector installed.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.

Connector

Connector type Molex PicoClasp 6 Pins
Mating part number 5013300600

Wiring Diagram

picoclasp 6 pin JCS net pinout

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


Analog Channel Interface

Specification

Input Single ended, ESD protected
Input voltage range 0V - 3.3V

Input filter 1st order, -3db 30kHz

NOTE:

This analog channel interface does NOT have an active buffer. Only connect low impedance sources.

Connector

Connector type 0.5mm PCB solder through holes

Pins Description

Pin Signal Description
+ +3V3A 3.3V analog out
- GNDA Analog return
s AN_IN Analog signal in

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.
