Lenze I51AE175B User Manual

9.2.5 Parameter access monitoring (PAM)
The parameter access monitoring can be used as basic protecon against a control loss of the
inverter. Monitoring is triggered if a parameter write access to a certain index does not take
place at regular intervals via the established communicaon connecon.
Precondions
This monitoring only works when the network control is acvated.
Except for the keypad, the monitoring can be used for all communicaon connecons, for
instance:
•
PC/Engineering Tool <--> inverter with USB module
•
PC/Engineering Tool <--> inverter with WLAN module
•
Controller <--> network <--> inverter with network opon
Details
For monitoring purposes, a non-zero value must be wrien into the "Keep-alive register"
0x2552:002 (P595.02) at regular intervals. The rst write access with a non-zero value ac-
vates monitoring. The intervals between the write accesses must not be higher than the me-
out me set in 0x2552:003 (P595.03). If no parameter write access takes place within the
me-out me, monitoring is triggered: The response selected in 0x2552:005 (P595.05) takes
place and the acon selected in 0x2552:005 (P595.05). In addion, the status bit 1 in
0x2552:006 (P595.06) is set to "1".
The error status can be le by a normal "error reset". Since monitoring connues to be acve
and the me-out me is not reset by the error reset, the inverter immediately changes again
to the error status. In order to prevent his, you have the following opons:
a)
Restore communicaon exchange.
b)
Set the monitoring response in 0x2552:004 (P595.04) to "No response [0]" or "Warning
[1]".
c)
Change over to local or exible control.

If the seng is non-zero, the monitoring is acve.

In order that the monitoring is not tripped, a non-zero value has to be
entered into this index at regular intervals. The temporal distances of
the write accesses must not be higher than the me-out me set in
0x2552:003 (P595.03).
