Fault tracing
CAUSE
Incorrect speed/frequency limit
parameter setting
Incorrect analog input AI signal
scaling
Incorrect analog output AO
signal scaling
Incorrect motor nominal power
setting
Fieldbus control has not been
activated.
Incorrect motor nominal speed/
frequency setting
Incorrect voltage to frequency
(U/f) ratio voltage setting.
It is not allowed to use MTAC
encoder module, frequency
input signal and frequency
output signal simultaneously.
WHAT TO DO
Check parameter settings. Check that following
applies:
2001 < 2002,
2007 < 2008,
2001/9908, 2002/9908, 2007/9907
2008/9907 are within range.
Check parameter group 13 ANALOGUE INPUTS
settings. Check that following applies:
1301 < 1302, 1304 < 1305.
Check parameter group 15 ANALOGUE OUTPUTS
settings. Check that following applies:
Check parameter 9909 setting. Following must apply:
1.1 < (9906 MOTOR NOM CURR ·
NOM VOLT · 1.73 / P ) < 3.0
N
Where P = 1000 · 9909 MOTOR NOM POWER (if
N
units are in kW)
or P = 746 · 9909 MOTOR NOM POWER (if units
N
are in HP).
Check fieldbus parameter settings. See chapter
Fieldbus control with fieldbus
Check parameter settings. Following must apply:
1 < (60 · 9907 MOTOR NOM FREQ /
NOM SPEED) < 16
0.8 < 9908 MOTOR NOM SPEED / (120 ·
MOTOR NOM FREQ / Motor poles) < 0.992
Check parameter 2610...2617
Disable frequency output, frequency input or
encoder:
- change transistor output to digital mode (value of
parameter 1804 = DIGITAL), or
- change frequency input selection to other value in
parameter groups 11 REFERENCE SELECT,
40 PROCESS PID SET 1, 41 PROCESS PID SET 2
and 42 EXT / TRIM PID, or
- disable (parameter 5002) and remove MTAC
encoder module.
