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:
• A parameter is set for fieldbus control (e.g. 1001
EXT1 COMMANDS = 10
(
COMM)), but 9802 COMM PROT SEL = 0.
1008 PAR PFAMODE Parameter values are inconsistent – 9904 MOTOR CTRL MODE must be = 3
(
SCALAR: SPEED), 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
1010 PAR PFA
OVERRIDE
Both the override mode and PFA are activated at the same time. These
modes are mutually incompatible, because PFA interlocks cannot be
observed in the override mode.
1011 PAR OVERRIDE
