A common scenario: A vertical milling machine with a heavy spindle head. When the operator executes a rapid downward move and then an emergency stop, the spindle head tries to decelerate. The kinetic energy of the heavy axis, combined with gravity (which pulls downward even during deceleration), overwhelms the braking resistor. Error 607 appears.
The SIMODRIVE 611 is now considered by Siemens (replaced by SINAMICS S120). However, thousands remain in service. For error 607: simodrive 611 error 607
Check the physical copper bars linking the modules. If a screw has vibrated loose, the physical connection will fail under high current demands, dropping the voltage. A common scenario: A vertical milling machine with
on the 7-segment display) occurs when the motor cannot reach its setpoint speed or position because it has hit its maximum voltage output, yet it is still drawing maximum current. Effectively, the drive is "maxing out" trying to move the motor but failing to do so. Siemens SiePortal 2. Common Causes Phase Failure: Error 607 appears
The SIMODRIVE 611 expects a strict order of enable signals:
| Condition | Action | |-----------|--------| | Mechanical binding | Repair mechanics | | Incorrect parameters | Reconfigure drive | | Motor winding short | Replace motor | | Drive current sensor failed | Replace drive module | | Intermittent 607 (once per week) | Likely parameter or cooling issue |
