GE DS200DTBBG1A Channel module

The velocity loop monitor will appear when the following conditions occur simultaneously: 

• The current command value is at the peak current limit 

• The difference between the actual velocity and the command velocity is larger than 10% of the maximum motor velocity. 

• actual speed > 1.25% of maximum speed 

• command and actual acceleration have different qualifying signs Cause: 1. Motor cable is connected incorrectly. 2. Defective controller section of the drive. 3. Defective feedback. 4. Velocity loop paramaterized incorrectly. 5. Incorrect commutation offset

Velocity Limit Value Exceeded (S-0-0092) 

Description: The actual velocity is monitored in torque regulation mode. This error is generated if the programmed velocity in the "S-0-0091, bipolar velocity limit value" parameter is exceeded by 1.25 times or a maximum of 100 Rpm. Cause: The load torque was smaller or larger than the torque command value for too long a time. This leads to an increase in the actual velocity up to the maximum possible motor velocity. Remedy: Check the primary control loop.

4 kHz Signal Error 

The 4kHz signal is synchronized with the software processing for creation of the resolver signal. This error message is created when synchronization occurs improperly. Cause: 1. The synchronization of the resolver controller voltage is invalid in regards to the software. 2. The error can be produced through an electrical discharge. Remedy: For 1. Exchange drive controller and return for testing. For 2. Power down and then on. If this in not successful; exchange drive controller.
