I have 4 KL-4030 drivers powered by a 36v 9.6a power supply. When I turn on the power supply all 4 drivers turn on with a red LED. I read some other KL drivers LED's turn red when there is a fault or problem. Is this true of the 4030 as well? All my stepper motors run fine, I'm just wondering if there is something wrong with the power or drivers? I've put this in the Automation Technologies forum as well. Just hoping to get an answer or suggestions to this.
