249151 <location>Cooling system: Conductivity has exceeded the fault
threshold
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The conductivity of the cooling liquid has exceeded the selected fault threshold (p0269[2]).
See also: p0261 (Cooling system, starting time 2), p0262 (Cooling system, fault conductivity delay
time), p0266 (Cooling system, feedback signals, signal source)
Remedy: Check the device to de-ionize the cooling liquid.
249152 <location>Cooling system: ON command feedback signal missing
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, 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 device for the cooling system.
249153 <location>Cooling system: Liquid flow too low
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, 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 (Cooling system status word)
Remedy: - check the wiring between the cooling system and the input terminal (Terminal Module).
- check the external control device for the cooling system.
249154 <location>Cooling system: Liquid leak is present
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The liquid leakage monitoring function has responded.
Caution:
Before this fault is re-parameterized as an alarm, you must ensure that the drive is shut down if cooling
water is lost.
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.
