WARNING 200, Fire mode
The frequency converter is operating in re mode. The
warning clears when re mode is removed. Refer to the
re mode data in the alarm log.
WARNING 202, Fire mode limits exceeded
While operating in re mode, 1 or more alarm conditions
that would normally trip the unit have been ignored.
Operating in this condition voids unit warranty. Cycle
power to the unit to remove the warning. Refer to the re
mode data in the alarm log.
WARNING 250, New spare part
The power card or switch mode power supply has been
exchanged. The frequency converter type code must be
restored in the EEPROM. Select the correct type code in
parameter 14-23 Typecode Setting according to the label on
the unit. Remember to select ‘Save to EEPROM’ to
complete.
WARNING 251, New typecode
The frequency converter has a new type code.
4.7 After Repair Tests
Following any repair to a frequency converter or testing of
a frequency converter suspected of being faulty, the
following procedure must be followed. Following the
procedure ensures that all circuitry in the frequency
converter is functioning properly before putting the unit
into operation.
1. Perform visual inspection procedures as described
in Table 4.1.
2. Perform static test procedures to ensure that
frequency converter is safe to start.
3. Disconnect motor cables from output terminals
(U, V, W) of frequency converter.
4. Apply AC power to frequency converter.
5. Give the frequency converter a run command and
slowly increase reference (speed command) to
approximately 40 Hz.
6. Use an analog voltmeter or a DVM capable of
measuring true RMS, measure phase-to-phase
output voltage on all three phases: U to V, U to
W, V to W. All voltages must be balanced within 8
V. If unbalanced voltage is measured, refer to
chapter 6.4.2 Input Voltage Test.
7. Stop the frequency converter and remove input
power. Allow 20 minutes for DC capacitors to fully
discharge.
8. Reconnect motor cables to frequency converter
output terminals (U, V, W).
9. Reapply power and restart frequency converter.
Adjust motor speed to a nominal level.
10. Use a clamp-on style ammeter, measure output
current on each output phase. All currents must
be balanced.
