Function that brings the motor to a standstill electrically after a specified time.

SS1(b) – Safe Stop 1 with Monitoring of the Deceleration Ramp

Function that brings the motor to a standstill electrically while monitoring deceleration.

SS1(a) – Safe Stop 1 with Control and Monitoring of the Deceleration Ramp

Function that brings the motor to a standstill electrically, monitoring deceleration behavior.

SS2(c) – Safe Stop 2 with Time Control

Brings motor to standstill, then monitors position after a time delay (SOS).

SS2(b) – Safe Stop 2 with Monitoring of the Deceleration Ramp

Brings motor to standstill, monitors deceleration, then monitors position (SOS).

SS2(a) – Safe Stop 2 with Control and Monitoring of the Deceleration Ramp

Brings motor to standstill, monitors deceleration behavior, then monitors position (SOS).

SOS – Safe Operating Stop

Prevents motor deviation from stop position by keeping motor in position.

SLA – Safely Limited Acceleration

Prevents movement from exceeding a specified acceleration value.

SLS – Safely Limited Speed

Prevents the drive from exceeding a specified speed.

SSR – Safe Speed Range

Monitors motor speed within parameterized speed limits.

SSM – Safe Speed Monitoring

Monitors whether the drive exceeds a specified speed.

SDI – Safe Direction

Prevents movement in an unintended direction of rotation.

SLI – Safely Limited Increment

Prevents movement from exceeding a specified increment.

SBC – Safe Brake Control

Provides a safe output signal for controlling an external brake.
