Motor Connections 



Ethernet Connectors

The Ethernet ports use standard Ethernet RJ45 CAT5e, M8-A or M8-D connectors depending on the motor variant. They are labeled IN and OUT but either port may be used. The CM1-T Ethernet connections will act as a TCP/IP switch. Multiple motors or other devices can be connected in a daisy chain configuration without the need to run back to a central switch for each ethernet device.

Power Connector

The power connector supplies 24V to the TCP/IP slave and the motor separately. These two can be tied together so both are off the same power supply.

The power connector is an M9 circular connector from Binder. The relevant parts numbers are

  • The CM1M9-4F-4000 is 24AWG with conductor resistance of 97.5Ω/km
  • The HF version with EXT-3D cable has a resistance of 91.1Ω/km

Colors indicated are for the standard CM1M9-4F-4000 power cable. 


There is no reverse polarity protection. Ensure the 24V power is connected correctly before powering the unit.


Maintaining Control power and switching off motor drive power will

  • retain motor position 
  • remove any ability for the motor to be driven (as power to the motor drive has been removed).

I/O Connector


Connecting a digital input to GND will produce a logical high on the device.

USB Connection

The USB connector is a standard micro USB and is used to update firmware. When it is plugged into a computer it will create a virtual serial port.

LEDs 

Link and Activity LEDs

The Link LED will be lit as long as there is a network connection. The activity LED will blink when there is data transfer to/from the motor.

System and Motor Status LED 

The system status LED provides feedback to the user on overall system status. The following states exist

IP Address Selector 


The IP address selector switches will only be active if not using DHCP. If a static IP is programmed with the final value as 0, the rotary selectors will choose the final octet of the IP address. 

For example:
