Troubleshooting Siemens Simodrive 611 Error 607: Causes and Solutions
The error code 607 (often appearing as A607 , E-A607 , or 300607 on a connected SINUMERIK CNC screen) directly relates to the drive's current control mechanism. simodrive 611 error 607
: Excessive mechanical load or axis jams that prevent the motor from moving, causing it to hit its current limit. DC Link Issues : Low or unstable DC link bus voltage. Diagnostic and Repair Steps
A physically loose terminal pin inside the orange power cable connector plug. Are there any showing on the drive or the CNC screen
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.
This error occurs when the drive's internal current regulator saturates. The control module tries to push the maximum allowable current to the servomotor to reach a specific speed or position, but it fails to achieve the desired feedback response within a set time frame. DC Link Issues : Low or unstable DC link bus voltage
Error 607 is rarely a random software glitch; it points to a physical bottleneck in power delivery, feedback loop interruption, or hardware degradation. The primary causes include: 1. DC Link Voltage Drop

: If the error migrates to the new axis channel on your CNC display, your issue is a physical motor winding failure or an intermittent cable break that only opens up under movement stress.
Check the DC link voltage on your drive system using a multimeter. If the voltage is zero, the drive is not receiving power from the infeed module, or the internal supply path is broken. 2. Inspect Internal Fuses
