Parameter Description
p0490 Invert probe
1)
(factory setting 0000bin)
Using the 3rd bit of the parameter value, invert the input signals of digital input 3
for the probe.
p0580 Probe
1)
Input terminal (factory setting 0)
Connect input of probe with a digital input.
p0581 Probe
1)
Edge (factory setting 0)
Edge for analyzing the probe signal for measuring speed list value
0: 0/1 edge
1: 1/0 edge
p0582 Probe
1)
Pulse per revolution (factory setting 1)
Number of pulses per revolution
p0583 Probe
1)
Maximum measurement time (factory setting 10 s)
Maximum measurement time for the probe If there is no new pulse before the
maximum measuring time elapses, the inverter sets the actual speed value in
r0586 to zero.
The time is restarted with the next pulse.
p0585 Probe
1)
Gear ratio (factory setting 1)
The inverter multiplies the measured speed by the gear ratio before displaying it
in r0586.
r0586 Probe 1) Speed list value
Result of the speed calculation
p2181 Load monitoring response
Response when evaluating the load monitor. For setting options, see Table 7-31
Response options for load monitoring (Page 254).
p2192 Load monitoring delay time (factory setting 10 s)
Delay time for evaluating load monitoring.
p2193 = 2 For load monitoring configuration,
see Table 7-30 Setting options for load monitoring (Page 250)
p3230 = 586 Load monitoring actual speed value (factory setting 0)
Result of the speed calculation with the evaluation of the speed monitoring.
p3231 Load monitoring speed deviation (factory setting 150 rpm)
Permissible speed deviation of load monitoring.
1)
The "Probe" subfunction calculates the speed from the pulse signal of the digital input.
For more information, see the List Manual (the parameter list and function diagram 8013).

p2181 = 0 Load monitoring deactivated (factory setting)
p2181 = 1 A07920 for torque/speed too low
p2181 = 2 A07921 for torque/speed too high
p2181 = 3 A07922 for torque/speed out of tolerance
p2181 = 4 F07923 for torque/speed too low
p2181 = 5 F07924 for torque/speed too high
p2181 = 6 F07925 for torque/speed out of tolerance
