Description and Recommended Corrective Action
Error internal to the drive . Contact your local Daikin sales representative and report the error number .
Error in the system . Contact your local Daikin sales representative and report the error number .
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)
*These are factory set and tested . Contact your local Daikin sales representative if there is a problem .
Parameter values are inconsistent . Check for the following:
• 2007 MINIMUM FREQ is negative, when 8123 PFA ENABLE is active .
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 .
*Not used with MicroTech III .
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 .
*Not used with MicroTech III .
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
• Where: P = 1000 * 9909 MOTOR NOM POWER (if units are kW)
n
or P = 746 * 9909 MOTOR NOM POWER (if units are HP, e .g . in US)
n
Parameter values are inconsistent . Check for the following:
• Extension relay module not connected and
• 1410...1412 RELAY OUTPUTS 4...6 have non-zero values .
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 .
Parameter values are inconsistent – 9904 MOTOR CTRL MODE must be = 3 (SCALAR: SPEED), when 8123 PFA
ENABLE is activated .
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
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 .
Override is enabled, but parameters are incompatible . Verify that 1701 is not zero, and (depending on 9904* value)
1702* or 1703* is not zero . *Not used with MicroTech III .
IO configuration is not complete – not enough relays are parameterized to PFA. Or, a conflict exists between Group 14,
parameter 8117*, NR OF AUX MOT, and parameter 8118*, AUTOCHNG INTERV . *Not used with MicroTech III .
IO configuration is not complete – the actual number of PFA motors (parameter 8127, MOTORS) does not match the
PFA motors in Group 14* and parameter 8118* AUTOCHNG INTERV . *Not used with MicroTech III .
IO configuration is not complete – the drive is unable to allocate a digital input (interlock) for each PFA motor
(parameters 8120* INTERLOCKS and 8127* MOTORS) . *Not used with MicroTech III .
