F49152 Cooling system: ON command feedback signal missing
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The feedback signal of the ON command of the cooling system is missing.
- after the ON command, the feedback signal has not been received within the selected starting time (p0260).
- the feedback signal has failed in operation.
See also: p0260 (Cooling system, starting time 1), r0267 (Cooling system status word)
Remedy: - check the wiring between the cooling system and the input terminal (Terminal Module).
- check the external Control Unit for the cooling system.
F49153 Cooling system: Liquid flow too low
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The drive converter cooling system signals that the cooling liquid flow is too low.
- after the ON command, the feedback signal has not been received within the selected starting time (p0260).
- in operation, the feedback signal has failed for longer than the permitted failure time (p0263).
See also: p0260 (Cooling system, starting time 1), p0263 (Cooling system fault liquid flow, delay time), r0267 (Cool-
ing system status word)
Remedy: - check the wiring between the cooling system and the input terminal (Terminal Module).
- check the external Control Unit for the cooling system.
F49154 (A) Cooling system: Liquid leak is present
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The liquid leakage monitoring function has responded.
See also: r0267 (Cooling system status word)
Remedy: - check the cooling system for leaks in the cooling circuit.
- check the wiring of the input terminal (Terminal Module) used to monitor leaking fluid.
Reaction upon A: NONE
Acknowl. upon A: NONE
F49155 Cooling system: Power Stack Adapter, firmware version too old
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: POWER ON
Cause: The firmware version in the Power Stack Adapter (PSA) is too old and does not support the liquid cooling.
Remedy: Upgrade the firmware.
F49156 Cooling system: Cooling liquid temperature has exceeded the fault threshold
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The cooling liquid intake temperature has exceeded the permanently set fault threshold.
Remedy: Check the cooling system and the ambient conditions.
A49170 Cooling system: Alarm has occurred
Drive object: A_INF, B_INF, SERVO, S_INF, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The cooling system signals a general alarm.
Remedy: - check the wiring between the cooling system and the input terminal (Terminal Module).
- check the external Control Unit for the cooling system.
