FAULT
CODE
FAULT NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
1000
PAR HZRPM
Parameter values are inconsistent. Check for any of the following:
2001 MINIMUM SPEED > 2002 MAXIMUM SPEED
2007 MINIMUM FREQ > 2008 MAXIMUM FREQ
2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: ---128/+128
2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: ---128/+128
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: --- 128/+128
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: --- 128/+128
1001 PAR PFA REFNG Parameter values are inconsistent. Check that 2007 MINIMUM FREQ is negative, when 8123 PFA ENABLE is active.
1002
PAR PFA IOCNF
Parameter values are inconsistent. The number of programmed PFA relays does not match with Interlock
configuration, when 8123 PFA ENABLE is active. Check consistency of RELAY OUTPUT parameters 1401 through
1403, and 1410 through 1412. Check 8117 NR OF AUX MOTORS, 8118 AUTOCHANGE INTERV, and 8120
INTERLOCKS.
1003
PAR AI SCALE
Parameter values are inconsistent. Check that parameter 1301 AI 1 MIN > 1302 AI 1 MAX and that parameter 1304 AI
2 MIN > 1305 AI 2 MAX.
1004
PAR AO SCALE
Parameter values are inconsistent. Check that parameter 1504 AO 1 MIN > 1505 AO 1 MAX and that parameter 1510
AO 2 MIN > 1511 AO 2 MAX.
1005
PAR PCU 2
Parameter values for power control are inconsistent: Improper motor nominal kVA or motor nominal power. Check the
following parameters:
1.1 < (9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1.73 / PN) < 2.6
Where: PN = 1000 * 9909 MOTOR NOM POWER (if units are kW) or PN = 746
* 9909 MOTOR NOM POWER (if units are HP, e.g., in US)
1006
PAR EXT RO
Parameter values are inconsistent. Check the extension relay module for connection and 1410 through 1412 RELAY
OUTPUTS 4 through 6 have non---zero values.
1007
PAR FBUS
Parameter values are inconsistent. Check that a parameter is set for field bus control (e.g., 1001 EXT1 COMMANDS =
10 (COMM)), but 9802 COMM PROT SEL = 0.
1008
PAR PFA MODE
Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must = 3 (SCALAR SPEED) when 8123 PFA
ENABLE activated.
1009
PAR PCU 1
Parameter values for power control are inconsistent or improper motor nominal frequency or speed. Check for both
of the following:
1 < (60 * 9907 MOTOR NOM FREQ / 9908 MOTOR NOM SPEED < 16
0.8 < 9908 MOTOR NOM SPEED / (120 * 9907 MOTOR NOM FREQ / Motor poles) < 0.992
1010 OVERRIDE/PFA
CONFLICT
Override mode is enabled and PFA is activated at the same time. This cannot be done because PFA interlocks cannot
be observed in the override mode.
