A05002 (N) Power unit: Air intake overtemperature
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for the air intake overtemperature has been reached. For air-cooled power units, the threshold
is 42 degrees Celcius (hysteresis 2 K). The response is set using p0290.
If the air intake temperature increases by an additional 13 K, then fault F30035 is output.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
Reaction upon N: NONE
Acknowl. upon N: NONE
A05003 (N) Power unit: Electronics board overtemperature
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for the overtemperature of the electronics module has been reached. The response is set using
p0290.
If the temperature of the electronics module increases by an additional 5 K, then fault F30036 is initiated.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
Reaction upon N: NONE
Acknowl. upon N: NONE
A05004 (N) Power unit: Rectifier overtemperature
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for the overtemperature of the rectifier has been reached. The response is set using p0290.
If the temperature of the rectifier increases by an additional 5 K, then fault F30037 is initiated.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the fan failed? Check the direction of rotation.
- has a phase of the line supply failed?
- is an arm of the supply (incoming) rectifier defective?
Reaction upon N: NONE
Acknowl. upon N: NONE
A05005 Cooling system: Cooling medium flow rate too low
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: Cooling system: Alarm - flow rate has fallen below the alarm value
Remedy:
A05006 (N) Power unit: Overtemperature chip to heatsink
Drive object: A_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause:
