Speed monitoring | |
Activation | Activation of speed monitoring

Index: 8550.1 | |
IEC name: – | |
Delay time | In acceleration and deceleration processes or during load peaks, the set current limit may be reached briefly. An unintentionally sensitive response of the speed monitoring can be prevented by a corresponding setting of the delay time. The current limit must be reached continuously for the duration of the delay time before the monitoring responds. |

IEC name: – | |
Reset time factor | When the setting limit of the speed controller is reached, a counter for the delay time is incremented every millisecond. If the speed controller moves away from the setting limit before the delay time expires, the counter is counted down again until 0 is reached. You can use this parameter to set a factor for how fast the counter is counted down when the control limit is no longer reached, compared to counting upwards. Normally, this factor is equal to 1, i.e. the counter is decremented every millisecond. With a factor of 2, the counter reading is reduced by 2 per millisecond, etc. |

Positioning lag error | |
Lag error window | Defines as from which lag error the drive signals a fault (drive train 1). The "Lag error window" parameter acts in FCB 09 and FCB 26. Information: The setting is valid for FCB 09 and FCB 26. For example, FCB 20 Jog mode has its own lag error window. |
Index: 8509.4 | |
Positioning lag error response | Specifies how the device responds to a lag error (lag error window exceeded, index 8509.4). The parameter "Response to lag error positioning" acts in FCB 09, FCB 10, and FCB 26. |
