Figure 6-22 Inverter response for discrepancy of the input signal for SS1 (as example: SS1 with braking
ramp monitoring)
The inverter does not set the error bit of the safety functions (= internal event).
After the tolerance time has expired, the inverter signals the discrepancy (message C01770
or C30770) but does not interrupt the braking operation for the motor.
