Safety Functions.

Safe stopping.

STO – Safe Torque Off = Safe shutdown of the drive controller

• Safe shutdown of the drive controller.
• Safely shuts off the energy supply to the motor.
• Ideal for a safe restart lock.

SS1 – Safe Stop 1

• Monitored braking with transition to STO.
• Detects errors already during braking.
• Ideal for low safety distances.
• Fallback level for all other safety functions at STOBER.

SS2 – Safe Stop 2

• Monitored braking with transition to SOS.
• Detects errors already during braking.
• Ideal for coupled axes and fast restarts.

•

Safe limiting

SSR – Safe Speed Range

• Freely selectable upper and lower speed limit.
• With optional dynamic tolerance.
• Ideal for speed range monitoring.

SLS – Safely Limited Speed

• Symmetrical monitoring at max. permitted speed.
• With optional dynamic tolerance.
• Ideal for monitoring and commissioning.

SDI – Safe Direction

• Locking of a direction of motion.
• Configurable tolerance range.
• Ideal for limit switch monitoring.

Safe Brake Management

SBC – Safe Brake Control

• Optional for one or two brakes.
• Regardless of brake type.
• Short circuit and cable break monitoring.
• Ideal for gravity-loaded axes.

SBT – Safe Brake Test

• Individually configurable test process.
• No obligation of documentation.
• Ideal for gravity-loaded axes.

Bedding in the brake

• Refresh instead of replace.
• Automatic bedding in of brakes.
• Ideal for increasing machine availability.

Safe monitoring

This function is purely for monitoring the safety functions mentioned and is identified by an -M connected to the abbreviation of the safety function.

• Ideal for variable safety responses in complex systems.
• Ideal for constant system protection.

Safe limiting: SLS-M, SSR-M, SDI-M

Safe position monitoring: SLI-M, SLP-M, SOS-M
