Function in the inverter
The STO function prevents the
supply of energy to the motor which
can generate a torque.
The SS1 function brakes the motor,
monitors the deceleration level of the
motor within defined limits and
initiates the STO function if the motor
speed falls below a defined limit
value.
An encoder to detect the motor
speed is not required.
The SLS function prevents the motor
exceeding the defined velocity/speed
limit.
An encoder to detect the motor
speed is not required.
The SSM function supplies a safe
output signal, to indicate whether the
motor speed is below a defined limit.
An encoder for measuring the motor
speed is not required.
The SDI function prevents the motor
shaft from rotating in the wrong
direction.
An encoder for measuring the motor
speed is not required
The SBC function supplies a safe
output signal to control an external
