Maintenance counters
The program has six different maintenance counters that can be configured to
generate an alarm when the counter reaches a pre-defined limit. The counter can be
set to monitor any parameter. This feature is especially useful as a service reminder.
There are three types of counters:
• Ontime counter. Measures the time a digital source (for example, a bit in a status
word) is on.
• Rising edge counter. This counter is incremented whenever the monitored digital
source changes state from 0 to 1.
• Value counter. This counter measures, by integration, the monitored parameter.
An alarm is given when the calculated area below the signal peak exceeds a
user-defined limit.

Load analyzer
Peak value logger
The user can select a signal to be monitored by the peak value logger. The logger
records the peak value of the signal along with the time the peak occurred, as well as
motor current, DC voltage and motor speed at the time of the peak.
Amplitude loggers
The drive has two amplitude loggers.
For amplitude logger 2, the user can select a signal to be sampled at 200 ms intervals
when the drive is running, and specify a value that corresponds to 100%. The
collected samples are sorted into 10 read-only parameters according to their
