7.1.16 Group 3.16: Mainten. 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. NOTE: 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 triggered respectively. Individual main-
tenance 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.
