Safety command for system start incorrect

What does F3150 mean?

The safety command issued to initiate a system start was incorrect or invalid. Safety systems require precise and validated commands to transition from a safe-stopped state to an operational state. An incorrect command means the system cannot safely initiate operation, preventing machine startup and maintaining a safe condition.

• Incorrect sequence of start commands from the safety controller
• Invalid data transmitted as a start command
• Communication error preventing correct start command reception
• Software bug in the safety controller's start logic
• Hardware fault on the input for the start command

1. 1

   Verify the safety PLC/controller program and logic for the system start command to ensure it is correctly configured and corresponds to the IndraDrive's safety input requirements.

2. 2

   Inspect the wiring and connections of the safety input signals (e.g., STO, SS1, SBC) at the IndraDrive MPx02's safety connector, checking for loose terminals, incorrect routing, or damaged cables.

3. 3

   Check the IndraDrive MPx02's safety parameters (e.g., S-0-0017, S-0-0036) in the drive's configuration software (e.g., IndraWorks) to confirm they match the external safety controller's expected commands and safety function settings.

4. 4

   Measure the voltage levels or signal status of the safety command inputs directly at the IndraDrive's safety terminals while attempting a system start, comparing them against the specified voltage ranges for active/inactive states.
