8.7.8.8 Sine Filter (P6.7.5)
When using an old motor or a motor that was not made to be used with an AC drive, it can be necessary to use a sine filter. A sine filter
makes the sine form of the voltage better than a dU/dt filter.
If a sine filter is used in the AC drive, set this parameter to
Connected
to put it into operation.
8.7.8.9 Pre-charge Mode (P6.7.6)
For an FI9 or a larger inverter unit, select
Ext.ChSwitch
to control an external charge switch.

8.7.9.2 Total Counters (S6.8.1)
The
Total counters
page (

operation days, and operation hours. The Total counters cannot be reset.
The Power On time counter (days and hours) always counts, when the AC power is on. The counter does not count when control unit
runs on +24 V only.
