ABB Master–Slave robots: power ON Master first or Slave?

We are using two ABB robot cabinets configured in a Master–Slave setup, where the Master robot is in one cabinet and the Slave robot is in another cabinet. Currently, both cabinets are powered using two separate power switches.

Is there a recommended power-ON sequence for this setup?
Should the Master cabinet be powered ON first followed by the Slave, or should the Slave be powered ON before the Master?
Also, what are the possible risks (e.g., calibration loss, communication errors) if the correct power sequence is not followed?

    Hello @akileswar1606,
    If your controller setup is a multimove setup, you need first the slave to be powered ON and second the master.
    If you power On the master first, you will get a system failure and errors saying second drive module is missing.
    To recover just power off all, and make sure to power on the slave before the master.

    I had not considered this being that type of master/slave setup, I thought it was referring to the communication protocol, like Devicenet.  I guess clarification would be nice.

    Ah, I see where you're coming from! The master/slave setup I mentioned here is specifically about the power-up sequence for the devices in a multimove configuration. In this case, the slave should be powered on first to avoid errors or system failure.

    You're right that 'master/slave' can also refer to communication protocols like DeviceNet or Profibus, where the master device controls the communication with the slave devices. But in this context, it's more about the sequence of powering on the devices, not the communication protocol.

    Hope that clears it up!
