I have two Bosch Rexroth inverters. The one with the integrated power supply works fine (XCD1-W2323) but the one connected to it without an integrated power supply (XMD1-W0606) gives an error while tyring to power on an axis (see attachents). While the XMD1-W0606 idles it gives the code: "A0013 ready for power on". This is strange since I connected the L+ and L- of both inverters and the supply voltage is correct. The drives connected to the W2323 work fine. Why is this happening?
Solved! Go to Solution.
The drive is in standard settings does not switch from bb to Ab on its own but awaits a Signal to to do so. Please check the corresponding how to"Suitably Power ON/OFF ctrlX DRIVE".
In the manual it states that I should configure bit 15 to S-0-0240 "DC Bus Power Control".
But when I try to do that I get the error "Invalid operation data: IDN is not supported, invalid bit number or bit combination". How can I solve this?
I have the bits configured in the CtrlX I/O engineering app.
You configured parameter S-0-0240 twice in your case. Once as complete parameter to transfer and once in the signal control word. As you already have it in your cyclic data you can of course use the bit directly out of there.
Please read the above mentioned How-To more carefully.
You tried to configure it now double wise:
The single parameter S-0-0240 in the cyclic data and the same one (S-0-0240) in the signal control word. This is not possible.
As well the S-0-2057 is configured in the cyclic data. this doesn´t work as this is no power supply unit like XVE, XVR, XCS or XCD.
