Action Validation rule Meaning Inverter state = off Inverter state is off by default. n=1 Can only occur as first instruction Inverter state = on Test must start with a Start instruction 0 <= Duration <= Durationmax Duration cannot be negative Acc RPMn+1 > RPMn Target speed must be greater than current speed Acc RPMn+1 < RPMmax Target speed must not exceed limit Inverter state = on Test must start with a Start instruction 0 <= Duration <= Durationmax Duration cannot be negative Dec RPMn+1 < RPMn Target speed must be less than current speed Dec RPMn+1 >= 0 Target speed may not be negative Inverter state = on Test must start with a Start instruction RPMn+1 = RPMn Target speed must be equal to current speed 0 <= Duration <= Durationmax Duration cannot be negative Inverter state = on Test must start with a Start instruction Stop RPMn = 0 Previous instruction must bring the drive to standstill Stop n = nmax Can only occur as last instruction Start Start Acc Acc Dec Dec Con Con Con Stop 4.3 Changing speed In cases where the acceleration and deceleration ramps are used, the next instruction would not be processed until the required speed is achieved. This may add to the overall duration of the test. 108
