Figure 5-23 SS1 with acceleration monitoring
Speed tolerance
As long as the speed is less, the inverter continuously adds the tolerance to the actual speed
so that the monitoring tracks the speed.
Shutdown speed acceleration monitoring
The inverter reduces the monitoring threshold until it reaches the value of the "Shutdown speed
acceleration monitoring".
Shutdown speed SS1 and delay time
The inverter safely switches off the motor torque with the STO function if one of the two
conditions is fulfilled:
● The actual speed reaches the value of the shutdown speed SS1.
● The delay time has expired.
