Frequently Asked Questions

What is the function of the Lenze SM100 Safety Module?

The Lenze SM100 Safety Module is designed to ensure safe torque off (STO) functionality, which is a protection against unexpected start-up of the drive. It is used in conjunction with Lenze 9400 Series Servo Drives to enhance safety during operation.

Can the SM100 Safety Module be used with any servo drive?

No, the SM100 Safety Module is specifically designed to be used with Lenze drive controllers of the L-force | 9400 series. Using it with other drives is considered inappropriate and may not ensure the desired safety functions.

What safety standards does the SM100 Safety Module comply with?

The SM100 Safety Module complies with Category 4 and Performance Level e (PL e) according to ISO 13849-1, as well as SIL 3 according to IEC 61508. These standards ensure the highest level of safety for controlling hazardous machine movements.

How is the SM100 Safety Module installed?

The SM100 Safety Module should be installed and commissioned by qualified and skilled personnel, following the safety engineering systems guidelines. It requires proper installation within the control cabinet and connection to the drive controller, adhering to the requirements of ISO 13849-1 and ISO 138492.

What are the voltage requirements for the SM100 Safety Module?

The SM100 Safety Module operates with a supply voltage of 24 V dc and is designed to be powered through a safely separated power supply unit (SELV/PELV).

Are there any specific commissioning procedures for the SM100 Safety Module?

Yes, during commissioning and after the replacement of the module, it is vital to check the safety function. No settings are required on the module itself, but certain settings must be configured in the basic device, such as the type of safety module.

What should be done if the safety function request is cancelled?

If the request for the safety function is cancelled, the drive will restart automatically. It is essential to provide external measures to ensure that the drive only restarts after a confirmation, as per EN 60204.

How often should the SM100 Safety Module be inspected?

The SM100 Safety Module should undergo periodic inspections to ensure the correct sequence of the safety-oriented functions. The inspection interval should not exceed one year, and the time intervals may depend on the application, the entire system, and the corresponding risk analysis.

What is the significance of the input and output terminals on the SM100 Safety Module?

The input and output terminals on the SM100 Safety Module, such as SIA, SIB, and GI, are used for two-channel sensor signal connections, while terminals like 24O, DO1, and GO are for non-safe feedback connections. These terminals are crucial for the module's safety functions and must be wired correctly.

What happens in the event of a short-circuit within the SM100 Safety Module?

In the event of a short-circuit of two power transistors within the SM100 Safety Module, a residual movement of the motor may occur. This residual movement must be considered in the risk analysis and appropriate measures taken to ensure safety.
