Program Continuation:

Axis %1 drive %2 power section heat sink temperature exceeded

%1 = NC axis number %2 = Drive number

The temperature of the power section is acquired from a temperature switch on the heatsink. 20 seconds after the heatsink temperature warning, drive shutdown is initiated immediately in order to avoid thermal damage to the power section (regenerative stop).

-    Mode group not ready.

-    The NC switches to follow-up mode.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

-    Channel not ready.

Please inform the authorized personnel/service department. Provide better ventilation of the drive modules, e.g. by means of:

Greater air throughput in the switching cabinet, if necessary cool the ambient air of the 611D modules.

Avoid numerous acceleration and deceleration operations in rapid sequence by modifying the workpiece programming.

Incorrect motor/power section dimensioning Excessive ambient temperature (see Planning Guide)

Exceeding of the installation height (see Planning Guide)

Excessive pulse frequency (see Planning Guide)

Defective module Fan failure

Observance of the minimum clearance over and under the power section (see Planning Guide)

Switch control OFF - ON.
