Kinetix 350 Servo Drive Torque-Off Feature
The Kinetix 350 servo drives are approved for use in safety-related applications. The drives are compatible with the ISO 13849-1 performance level d (PLd), classified as safety category 3. The certification defines the de-energized state as the safe state.
The safe torque-off feature is not an ultimate safety control system. Each control system component must be carefully chosen and configured, considering the proven safety practices to ensure safe operation. The safe torque-off circuit removes the power from gate firing circuits (IGBTs) and stops the patterned switching, thus restricting the AC power delivery to the motor. This safety circuit can be used with other safety devices to achieve a similar goal, stopping the drive and constraining restarting. It should be noted that this safety feature is related to the mechanical stop of the drive system or the affected machine part, and it does not help with electrical safety in any way. To practice work safety, during diagnosis or maintenance, electric power to the motor should be disconnected, and the voltage level should be tested to avoid an electric hazard.
The Kinetix 350 servo drives have the torque-off circuit enabled by default. This feature can be disabled if not required by adding jumper wires among the terminals as specified in the manual.
Kinetix 350 Servo Drive Troubleshooting
With the Kinetix 350 servo drive, troubleshooting is made easy by providing fault & status indicators and descriptive messages that help identify the fault and its reason.
Status Indicators
Four-Digit Display Messages
There is a four-digit seven-segment display that shows the status and fault-related messages. The text strings are scrolled on display. The messages are displayed on the screen with a pre-defined priority. A higher-priority message is displayed first. The codes and symbols on display correspond to a specific device condition which then can be investigated.
Error Codes
There are two types of error codes displayed on the status indicator display.
- E38: It represents a memory module function error that can be resolved via a module replacement.
- E76: It corresponds to a blank memory module, which requires formatting by pushing and holding the enter button on the front panel until the system status changes to busy.
Fault Codes
The fault-related codes and messages are displayed and scrolled on the four-digit display, which helps identify the system's anomaly. The fault codes are categorized as follows.
- S xx or Sc xx: A condition that resists drive enabling
- F xx or Fc xx: Standard axis fault
- L xxx: Errors occurring during the boot process
- P xxx: Errors occurring during the Power-on Self Test
- Ic xx: Errors occurring in the initialization process and preventing normal operation
- nF xx: A node-fault error that impacts the servo drive
Status Indicators
There are four status indicators: the drive status indicator, axis status indicator, network status indicator, and Ethernet communication status indicator. These indicators represent various conditions by flashing, switching, and holding states in red and green colors.
General System Behavior
Many system events highlight a drive condition that does not lead to a fault code but requires troubleshooting, as it can improve the system's performance. The conditions include an unstable axis, motor not responding to a velocity command, no rotation, motor overheating, noise on motor feedback signal wires, and abnormal noises.
