AND RECOMMENDED

CODE
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
Parameter values are inconsistent.
The number of programmed
PFA relays does not match with Interlock
PAR PFA IOCNF
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
2MIN
> 1305AI 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
AO2MIN
> 1511AO2MAX.
1005
Parameter values for power control are inconsistent:
Improper
motor nominal kVA or motor nominal power. Check the
following
parameters:
PAR PCU 2
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
Parameter values for power control are inconsistent
or improper
motor nominal frequency
or speed. Check for both
of the following:
PAR PCU 1
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
Override mode is enabled
and PFA is activated at the same time. This cannot be done because PFA interlocks
cannot
CONFLICT
be observed
in the override
mode.
