Overview of Alarms

SINAMICS-Alarms

<location>Cooling system: Power Stack Adapter, firmware version too

Drive object:

A_INF, B_INF, S_INF, SERVO, VECTOR

Acknowledge:

The firmware version in the Power Stack Adapter (PSA) is too old and does not support the liquid cool-

Upgrade the firmware. Check EEPROM data.

<location>Cooling system: Cooling liquid temperature has exceeded the

fault threshold

Drive object:

A_INF, B_INF, S_INF, SERVO, VECTOR

Acknowledge:

The cooling liquid intake temperature has exceeded the permanently set fault threshold.

Check the cooling system and the ambient conditions.

<location>Cooling system: Alarm has occurred

Drive object:

A_INF, B_INF, S_INF, SERVO, VECTOR

Acknowledge:

The cooling system signals a general alarm.

- check the wiring between the cooling system and the input terminal (Terminal Module).

- check the external control device for the cooling system.

<location>Cooling system: Conductivity has exceeded the alarm

Drive object:

A_INF, B_INF, S_INF, SERVO

Acknowledge:

The conductivity of the cooling liquid has exceeded the selected alarm threshold (p0269[1]).

See also: p0261 (Cooling system, starting time 2), p0262 (Cooling system, fault conductivity delay

time), p0266 (Cooling system, feedback signals, signal source)

Check the device to de-ionize the cooling liquid.

<location>Cooling system: Conductivity has exceeded the alarm

Drive object:

Acknowledge:

The conductivity monitoring of the cooling liquid is set (r0267 bit 7, from p0266 index 7).
