Getting 400 alarm on power up. Diagnostic 721.7 = overload either with board or motor. I presume 721 is for Z axis.?? If this correct, then problem is with board as the motor is not connected, in fact it has been removed from machine.
Going down the troubleshooting tree the OH LED is not on, only the green is lit.
Next step says check the S1 setting. Cause 1 says "if S1 is incorrect the amp gets overheated just by powering up". Not sure how to check the setting. Haven't found info in the amplifier manual(GFZ-65005E/07). A little help, please.
An aside.https://www.practicalmachinist.com/...-continuation-0tc-cpa9-board-question-379396/ I managed to get the PLC/PMC parameters loaded in a normal manner: LSK flashing, press EOB and input,INPUT flashes and parameters load. Tried to load diagnostic parameters but LSK wouldn't come on. Anyway, there are a bunch of entries in the table. Haven't checked them against my back up list. I suspect that there may be a bad connection at the DP25 plug. Wire side looks pretty corroded.
