5.11 U: Monitor Parameters

Monitor parameters let the user view various aspects of drive performance using the digital operator display. Some monitors
can be output from terminals FM and AM by assigning the specific monitor parameter number (Uo-oo) to H4-01 and H4-04.
Refer to H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection on page 304
assigning functions to an analog output.

U1: Operation Status Monitors

Status monitors display drive status data such as output frequency and output current.

U2: Fault Trace

Use these monitor parameters to view the status of various drive aspects when a fault occurs.
This information is helpful for determining the cause of a fault.

U3: Fault History

These parameters display faults that have occurred during operation as well as the drive operation time when those faults
occurred. Refer to U3: Fault History on page 576

U4: Maintenance Monitors

Maintenance monitors show:
• Runtime data of the drive and cooling fans and number of Run commands issued
• Maintenance data and replacement information for various drive components
• kWh data
• Highest peak current that has occurred and output frequency at the time the peak current occurred
• Motor overload status information
• Detailed information about the present Run command and frequency reference source selection
