u U1: Operation Status Monitors
Status monitors display drive status data such as output frequency and output current. Refer to U1: Operation Status
Monitors on page 309 for a complete list of U1-oo monitors and descriptions.
u 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.
Refer to U2: Fault Trace on page 311 for a complete list of
U2-oo monitors and descriptions.
U2-oo monitors are not reset when the drive is initialized.
Refer to o4-11: U2, U3 Initialization on page 178 for instructions
on how to reset these monitor values.
Note: Fault histories are not kept when CPF00, CPF01, CPF06, CPF24, oFA00, oFb00, oFC00, Uv1, Uv2, or Uv3 occur.
u 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 312 for a complete list of U3-oo monitors and descriptions.
U3-oo monitors are not reset when the drive is initialized. Refer to o4-11: U2, U3 Initialization on page 178 for instructions
on how to reset these monitor values.
Note: Fault histories are not kept when CPF00, CPF01, CPF06, CPF24, oFA00, oFb00, oFC00, Uv1, Uv2, or Uv3 occur.
u 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
