Simodrive 611 Error 607

In Siemens terminology, Error 607 is a . It occurs when the internal DC bus voltage of the drive inverter rises above the maximum permissible threshold. Under normal operation, the rectifier converts AC mains input into DC voltage (typically around 600V DC for a 400V AC system). The drive’s internal logic monitors this voltage constantly.

Use a Megohmmeter (Megger) at 500V or 1000V to test insulation resistance from each phase to the motor chassis ground. Any reading below 10 Megohms indicates insulation breakdown or moisture ingress.

When Error 607 occurs, the system immediately drops the axis enable signal, triggering secondary CNC contouring or axis hardware faults (such as Sinumerik alarms 25201 or 380500) to protect the machine tool from severe structural and electrical damage. Anatomy of Error 607: What Causes It?

Markus wiped his hands on a rag. “The new IGBT is rated for fifty thousand hours. The solder joints are better than factory. I’d say… longer than the contract.”

The (often visible on the LED display as E-A607 , E-B607 , or CNC alarm 300607 ) indicates a "Current Controller Output Limited" fault. This critical hardware-protection error triggers when the drive control module attempts to force the maximum allowable current into the motor, but the system is physically unable to establish or maintain that current level.

Excessive friction on the slideways, a jammed ballscrew, or a heavy load can prevent the motor from reaching its target position in time. In Siemens terminology, Error 607 is a

Fatima’s frown finally cracked into something resembling relief. “You just saved us. How long will it last?”

Turn off the power, remove the front control card from the faulted drive, and swap it with an identical card from a working axis. Note: Ensure you backup parameters or swap the memory modules if applicable. If the fault moves with the card, the control card is defective.

One of the main causes for an absence of DC link voltage is a failure of the internal fuses (such as the high-amperage 315A fuses found in larger infeed/drive modules).

While Lena fetched the old ruggedized Toughbook, Markus retrieved a battered metal briefcase from his locked tool chest. Inside, nestled in foam cutouts, were not new parts, but tools: high-voltage probes, a desoldering station, and a set of matched IGBT transistors. In the old days, before the era of “replace, not repair,” men like Markus fixed these units. But Siemens had long stopped selling the individual components.
