Table 7- 23 Setting speed deviation monitoring
Parameter Description
P2193 = 2 Load monitoring configuration (factory setting: 1)
2: Speed and load failure monitoring
P2192 Load monitoring delay time (factory setting 10 s)
Setting the delay time for evaluation of load monitoring
P2181 Load monitoring response (factory setting 0)
Setting the response for evaluation of load monitoring
P3231 Load monitoring speed deviation (factory setting 150 rpm)
Permissible speed deviation of load monitoring
P0704 = 51 Pre-assignment of digital input
51: Load monitoring, failure detection
P0581 Probe edge (factory setting 0)
Setting the edge for evaluation of the probe signal to measure actual speed value
0: 0/1 edge
1: 1/0 edge
P0582 Probe pulses per revolution (factory setting 1)
Setting the number of pulses per revolution
P0583 Maximum probe measuring time (factory setting 10 s)
Setting the maximum measuring time for the probe. If there is no new pulse before
the maximum measuring time elapses, the actual speed value in r0586 is set to
zero.
With the next pulse, the time is restarted.
P0585 Probe gear factor (factory setting 1)
The measured speed is multiplied by the gear factor before being displayed in
r0586.
P0490 Invert probe (factory setting 0000bin)
The 3rd bit of the parameter value inverts the input signals of digital input 3 for the
probe.
