5.12 U: Monitor Parameters

5.12 U: Monitor Parameters

Monitor parameters let the user view various aspects of drive performance using the HOA keypad 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 131

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.
U2-oo monitors and descriptions.
U2-oo monitors are not reset when the drive is initialized.
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 279
U3-oo monitors are not reset when the drive is initialized.
Note: Fault histories are not kept when CPF00, CPF01, CPF06, CPF24, oFA00, oFb00, oFC00, Uv1, Uv2, or Uv3 occur.
