8.1.16 Group 3.16: Maintenance Counters
The maintenance counter is a way of indicating the
operator that maintenance needs to be carried out.
For example, a belt needs to be replaced or oil in a
gearbox should be changed.
There are two different modes for the maintenance
counters, hours or revolutions*1000. The counters
are only incremented during Run mode in either case.
Revolutions are based on motor speed
which is only an estimate (integration
every second).
When the counter exceeds the limit an alarm or fault
will be trigged respectively. Individual maintenance
alarm and fault signals can be connected to a digital/
relay output.
When maintenance has been carried out the counter
can be reset through either a digital input or a
parameter B3.16.4.
