MAINTENANCE COUNTERS
A maintenance counter tells you that maintenance must be done. For example, it is
necessary to replace a belt or to replace the oil in a gearbox. There are 2 different modes for
the maintenance counters, hours or revolutions*1000. The value of the counters increases
only during the RUN status of the drive.
WARNING!
Do not do maintenance if you are not approved to do it. Only an approved electrician
can do maintenance. There is a risk of injury.
NOTE!
The revolutions mode uses motor speed, which is only an estimate. The drive
measures the speed every second.
When the value of a counter is more than its limit, an alarm or a fault shows. You can
connect the alarm and fault signals to a digital output or a relay output.
When the maintenance is completed, reset the counter with a digital input or parameter
P3.16.4 Counter 1 Reset.
P3.16.1 COUNTER 1 MODE (ID 1104)
Use this parameter to enable the maintenance counter.
