Information About 6SL3244-0BB12-1FA0

The 6SL3244-0BB12-1FA0 is a Sinamics G120 Control Unit. This unit features a Safe Torque Off (STO) function that prevents energy from being supplied to the motor, which can generate torque. This function can be used in several ways. It can be used with an Emergency Stop button so that when it is pressed, the stationary motor does not start. It can also be used with a central Emergency Stop button to ensure that several drives cannot unintentionally start. The module functions by recognizing the selection of STO via a fail-safe input or the safe communication PROFIsafe. The converter then safely switches off the torque of the connected motor. If no motor brake is present, the motor coasts to a standstill. If a motor holding brake is in use, the converter closes the brake immediately after selecting STO.

The Safe Stop 1 (SS1) is another function of the 6SL3244-0BB12-1FA0. The SS1 function brakes the motor, monitors the magnitude of the motor deceleration within defined limits, and initiates the STO function if the motor speed falls below a specified value. The SS1 function brakes the motor and monitors its absolute speed. If the motor speed is low enough, the converter safely switches off the motor torque using STO.

The third function of the 6SL3244-0BB12-1FA0 is Safely Limited Speed (SLS). The SLS function prevents the motor from exceeding the defined speed limit. SLS monitors the absolute value of the actual speed and limits the speed to values below the monitoring threshold. The Safe Direction Function (SDI) prevents the motor shaft from moving in the wrong direction. It does this by monitoring the actual direction of rotation, and also limits the speed to values in the permissible direction. The Safe Speed Monitor (SSM) function supplies a safe output signal to indicate whether the motor speed lies below a defined limit. SSM cannot be selected or deselected, it is only active when the monitoring velocity is > 0 for SSM. The converter then compares the load speed with the speed limit and signals if the limit value has fallen below the high-level control.
