Code SP0009: Main circuit overload/IPM overheat

Amplifier LED display: 09 Also shown as: SP0009 (15i), SP9009 (30i/31i/32i), SP9009 (0i-D) Cause: The temperature of the heat sink of the Spindle Amplifier main circuit has risen abnormally. This alarm is issued for αi SP22, αi SP30HV and later. With αi SP2.2 to αi SP15 and αi SP5.5HV to αi SP15HV, however, Alarm 12 is issued for the same cause. (1) If this alarm is issued during cutting (the heat sink temperature is high) (a) If this alarm is issued when the load meter reads a value below the continuous rating of the amplifier, check the cooling state of the heat sink. <1> If the cooling fan is stopped, check the power supply (connector CX1A/B). If the cooling fan is still inoperative, replace the Spindle Amplifier with a new one. <2> When the ambient temperature is higher than the specified temperature, lower the ambient temperature to satisfy the specification. (b) When this alarm is issued because the load meter reads a value above the continuous rating of the amplifier, improve the use method. (c) When the heat sink on the back of the amplifier is too dirty, clean the heat sink, for example, by blowing air. Consider the use of a structure that prevents the heat sink from being directly exposed to coolant. (2) If this alarm is issued under a light load (the heat sink temperature is high) (a) When the frequency of acceleration/deceleration is too high Set such a use condition that the average including output at acceleration/deceleration does not exceed the continuous rating. (b) The parameters specific to the motor are not set correctly. Referring to "FANUC AC SPINDLE MOTOR αi series Parameter Manual (B-65280EN)," check the motor-specific parameters. (3) Poor installation of the control printed-circuit board Be sure to push the faceplate as far as it will go. (This alarm may be displayed if one of the connectors for connection between the control printed-circuit board and power printed-circuit board is detached.) (4) If this alarm is issued when the heat sink temperature is low Replace the Spindle Amplifier.
