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
(factory setting 0)
Response for evaluating load monitoring.
0
Load monitoring disabled
1
A07920 for speed too low
2
A07921 for speed too high
3
A07922 for speed outside tolerance
4
F07923 for speed too low
5
F07924 for speed too high
6
F07925 for speed outside tolerance
p2192
Load monitoring delay time
(factory setting 10 s)
Delay time for evaluating load monitoring.
p2193 = 2
Load monitoring configuration
(factory setting: 1)
2: Speed deviation and load failure monitoring.
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.
