Issue 01/06 | Faults and Alarms |
F0090 Signal loss, encoder | STOP II |
Quit
Refer to F0001
Cause
-encoder signal between the encoder and inverter is interrupted
-excessively large difference between the setpoint (reference) and actual frequency
Diagnosis & Remedy
Please check the following:
-is there an integrated encoder? If there is no integrated encoder, then set P0400 = 0 and select the operating mode sensorless
-the connection between the encoder and the inverter
-is the encoder faulty? (select P1300 = 0, operation with fixed speed, check the encoder signal in r0061)
-increase the encoder signal threshold in P0492, P0494
F0101 Stack overflow | STOP II |
Quit
Refer to F0001
Cause
-software error or processor failure
Diagnosis & Remedy
-
F0221 PID feedback below the minimum value | STOP II |
Quit
Refer to F0001
Cause
-PID feedback below the minimum value P2268.
Diagnosis & Remedy
-change value of P2268.
-set feedback gain.
F0222 PID feedback above maximum value | STOP II |
Quit
Refer to F0001
Cause
-PID feedback above maximum value P2267.
Diagnosis & Remedy
-change value of P2267.
-set the feedback gain.
F0422 No load applied to inverter | STOP II |
Quit
Refer to F0001
Cause
No Load is applied to the inverter.
As a result, some functions may not work as under normal load conditions.
F0450 Failure BIST tests | STOP II |
Quit
Refer to F0001
Cause
-r0949 = 1:
-r0949 = 2:
-r0949 = 4: Several function tests were unsuccessful
-r0949 = 8: Several tests
-r0949 = 16: Failure of the internal RAM at the
Diagnosis & Remedy
-the drive is functional, but several functions are not correctly executed.
-replace the drive
