SimpleMotion V2 communication link and Argon drives use RJ45 connectors and cables as physical connection standard.
RJ45 is well known from Ethernet connectors and same cables may be used with SimpleMotion wiring.
Contents
Bus properties
SimpleMotion V2 uses RS485 electrical serial communication standard for all data transfer. Some main benefits of using RS485 are:
- Multidrop buses possible (up to 32 devices in single serial link)
- High reliability due to differential signaling
- High data rates and long cable lengths possible
- Easy to interface even from smallest microcontrollers with UART
- Low wire count, only 2 signal wires + ground needed
- Bidirectional data transfer (receive & transmit) in one wire pair
- Cabling with standard RJ45 Ethernet cables
As default SimpleMotion V2 uses 460800 BPS bitrate and can deliver over 1000 motion commands per second.
 | Don't use crossover cables in SimpleMotion V2 system |
PC connection
SimpleMotion V2 devices can be controlled and configured from PC computer by the help of compatible RS485 adapter. The most common way is to use USB to SimpleMotion V2 adapters such as:
- SimpleMotion V2 USB adapter
- DIY SimpleMotion V2 adapter
- Compatible third party adapters
- PCI-e / PCI RS485 adapters with at least 460.2k bps speed support
- Ethernet RS485 adapters with at least 460.2k bps speed support.
- Moxa NPort 5xxx devices have been verified to work reliably with SimpleMotion through their virtual COM port over Ethernet driver.
- FTDI USB chip based RS485 devices
Using SMV2 port as E-stop & Enable input
In SMV2 compatible drives, the SMV2 connector acts also as emergency stop or Safe torque off input. User may connect a e-stop button directly at the end of device chain to gain reliable stopping mechanism for all linked devices.
Wiring with SMV2BRK
The preferred method to wire STO and Enable signals to SM bus is to add a SMV2BRK break out board at the end of bus chain. SMV2BRK acts as RS485 termination resistor and a wire terminal for STO and Enable signals with easy interfacing to switches.
For commissioning of SMV2BRK, see it's dedicated SMV2BRK page.
Wiring with IONICUBE devices
IONICUBE motherboards have on broad routing from RJ45 connector to user accessible wire terminals. When using these motherboards, see IONI & IONICUBE user guide for wiring.
Wiring with bare RJ45 cable
To terminate SMV2 bus and connect switches without SMV2BRK, see SimpleMotion V2 termination with bare cable.
