LIMITS
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 proper range
(> 50)
• 2002
MAXIMUM SPEED / 9908 MOTOR NOM SPEED is outside proper range
(> 50)
• 2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is outside proper range
(> 50)
• 2008
MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside proper range
(> 50)
1001
PAR PFAREFNG Parameter values are inconsistent. Check for the following:
• 2007
MINIMUM FREQ is negative, when 8123 PFA ENABLE is active.
1002 RESERVED

1003
PAR AI SCALE Parameter values are inconsistent. Check for any of the following:
• 1301
AI 1 MIN > 1302 AI 1 MAX.
• 1304 AI 2 MIN > 1305 AI 2 MAX.
1004 PAR AO SCALE Parameter values are inconsistent. Check for any of the following:
• 1504
AO 1 MIN > 1505 AO 1 MAX.
• 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 for the following:
• 1.1 <
(9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1.73 / P
N
) < 3.0
•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
EXT ROMISSING 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
FBUSMISSING
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
PFAWOSCALAR
Parameter values are inconsistent – 9904 MOTOR CTRL MODE must be = 3
(
SCALAR: SPEED), when 8123 PFA ENABLE is activated.
