Parameters 189
Hysteresis
Action is taken whenever the signal rises above the value
defined by the limit + 0.5
·
hysteresis range (
). The action is deactivated when the
signal falls below the value defined by the limit - 0.5
·
hysteresis range.
7
Selects whether the drive generates a fault, warning or
neither when the value monitored by signal supervision 4
exceeds its limits.
Note:
This parameter does not affect the status indicated by
.
No action
No warning or fault generated.
0
Warning
Warning
is generated.
1
Fault
Drive trips on fault
2
Fault if running
Drive trips on fault
if the motor is
running.
3
Selects the signal to be monitored by signal supervision
function 4.
For the available selections, see parameter
Defines a filter time constant for the signal monitored by
signal supervision 4.
0.000 s
0.000 … 30.000 s
Signal filter time.
1000 = 1 s
Defines the lower limit for signal supervision 4.
0.00
-21474836.00…
21474836.00
Low limit.
-
Defines the upper limit for signal supervision 4.
0.00
-21474836.00…
21474836.00
Upper limit.
-
Defines the hysteresis for the signal monitored by signal
supervision 4.
0.00
0.00…100000.00
Hysteresis.
-
Selects the mode of signal supervision function 5. Determines
how the monitored signal (see parameter
) is compared
to its lower and upper limits (
respectively).
The action to be taken when the condition is fulfilled is
selected by
.
Disabled
Signal supervision 5 not in use.
0
Low
Action is taken whenever the signal falls below its lower limit. 1
High
Action is taken whenever the signal rises above its upper
limit.
2
Abs low
Action is taken whenever the absolute value of the signal falls
below its (absolute) lower limit.
3
Abs high
Action is taken whenever the absolute value of the signal
rises above its (absolute) upper limit.
4
Both
Action is taken whenever the signal falls below its low limit or
rises above its high limit.
5
Abs both
Action is taken whenever the absolute value of the signal falls
below its (absolute) low limit or rises above its (absolute) high
limit.
6
No.
