Speed Limit; Torque Limit; Zero Speed Clamp - Siemens SINAMICS V90 Operating Instructions Manual

The following table shows you in details:
CCWE
Note
In S mode or T mode, when the servo motor is ready to run, signal CWE or CCWE is a must
to start running the motor.
For more information about signals CWE and CCWE, refer to "DIs (Page 90)".

Zero speed clamp

The function of zero speed clamp is used to stop motor and lock motor axis when motor
speed setpoint is below a parameterized threshold level (p29075).
This function is available only when the analog input 1 is used as the source of speed
setpoint. The digital input signal ZSCLAMP is used to activate this function. When both
motor speed setpoint and motor actual speed are below the parameterized threshold level
and signal ZSCLAMP is logic "1", the motor is locked. Drive exits from clamping state either
when the motor speed setpoint is above the threshold level or when the signal ZSCLAMP is
logic "0".
