Parameterisation and evaluation of the monitoring function
The Ixt monitoring function can be parameterised and evaluated via the following indices. Here, a
warning limit and an error limit can be set for each PT1 timing element.
• If the warning threshold (Lenze setting: 95 %) is exceeded, a warning is output in order that the
master is still able to respond if required.
• If the error threshold is exceeded (Lenze setting: 101 %), the inverter is switched off for
protecting the device and generates an error message.

Note!
Though continuous operation over 100 % is allowed for by the Ixt monitoring function,
this is nevertheless an impermissible working point!
