COUNTERS
The VACON
®
AC drive has different counters based on the operation time of the drive and the
energy consumption. Some of the counters measure total values and some can be reset.
The energy counters measure the energy that is taken from the supply network. The other
counters are used to measure, for example, the operation time of the drive or the runtime of
the motor.
It is possible to monitor all the counter values from the PC, keypad or fieldbus. If you use the
keypad or the PC, you can monitor the counter values in the Diagnostics menu. If you use
fieldbus, you can read the counter values with the ID numbers. In this chapter, you find data
on these ID numbers.
