PAR PCU
2 Parameter values for power control are
inconsistent: Improper motor nominal kVA or
motor nominal power. Check for the
following:
• 1.1 < (9906
MOTOR NOM CURR
* 9905
MOTOR NOM VOLT
* 1.73 / P
N
) < 2.6,
where: P
N
= 1000 * 9909
MOTOR NOM
POWER
(if units are kW)
or P
N
= 746 * 9909
MOTOR NOM POWER
(if
units are HP, e.g. in US).
1006
PAR EXT RO
Parameter values are inconsistent. Check
for the following:
• extension relay module not connected
and
• 1410…1412
RELAY OUTPUTS
4…6 have
non-zero values.
1007
PAR FBUS
Parameter values are inconsistent. Check
for and correct the following:
• A parameter is set for fieldbus control
(e.g. 1001
EXT
1
COMMANDS
= 10 (
COMM
)),
but 9802
COMM PROT SEL
= 0.
1008
PAR PFA MODE
Parameter values are inconsistent –
9904
MOTOR CTRL MODE
must be =
3 (
SCALAR
:
FREQ
) when 8123 PFA
ENABLE
is
activated.
1009
PAR PCU
1 Parameter values for power control are
inconsistent: 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.

PAR PFA
&
OVERRIDE
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.
