WHAT TO DO
Write down fault code and contact your local Daikin representative .
Check parameter settings .
Check that following applies:
• 2007 MINIMUM FREQ < 2008 MAXIMUM FREQ • 2007 MINIMUM FREQ /
9907 MOTOR NOM FREQ and 2008 MAXIMUM FREQ / 9907 MOTOR NOM
FREQ are within range .
Check parameter Group 81: PFA settings .
Check that following applies:
• 2007 MINIMUM FREQ > 0 when 8123 is ACTIVE or SPFC ACTIVE .
Check parameter Group 13: Analog Inputs settings .
Check that following applies:
• 1301 MINIMUM AI1 < 1302 MAXIMUM AI1
• 1304 MINIMUM AI2 < 1305 MAXIMUM AI2 .
Check parameter Group 15: Analog Outputs settings .
Check that following applies:
• 1504 MINIMUM AO1 < 1505 MAXIMUM AO1 .
Check parameter 9009 setting .
Following must apply:
• 1 .1 < (9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1 .73 / PN)
< 3 .0 where PN = 1000 * 9909 MOTOR NOM POWER (if units are in kW)
or PN = 746 * 9909 MOTOR NOM POWER (if units are in hp) .
Check parameter settings .
Check that following applies:
• Relay Output Extension Module MREL-0 is connected to the drive .
• 1402...1403 RELAY OUTPUT 2...3 and 1410 RELAY OUTPUT 4 have
non-zero values . See MREL-01 Relay Output Extension Module
User's Manual (3AUA0000035974 [English]) .
Check fieldbus parameter settings.
Check parameter settings .
Following must apply:
• 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
Check parameter settings .
Following must apply:
• There are enough relays parameterized for PFC .
• No conflict exists between parameter Group 14: Relay Outputs, parameter
8117 NR OF AUX MOT and parameter 8118 AUTOCHNG INTERV .
Check parameter settings .
Following must apply:
• The actual number of PFC motors (parameter 8127 MOTORS) matches
the PFC motors in parameter Group 14: Relay Outputs and parameter
8118 AUTOCHNG INTERV .
See parameters 8120 INTERLOCKS and 8127 MOTORS, page 93 .
