SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
• Error in actual current measurement (if necessary, replace 611D power section or con-
troller module)
• Incorrect power section module (1/2 axis)
• Check the contact between the controller module and the power section
• Check the contact between the fixing screw and the controller module
Switch control OFF - ON.
Axis %1 drive %2 measuring function active
%1 = NC axis number
%2 = Drive number
The measuring function (e.g. frequency response measurement was active during the
switching on operation (power supply start-up active). Illegal activation of the measuring
function may have occurred internally.
- NC not ready.
- Channel not ready.
- Channel not ready.
- NC Stop on alarm.
- NC Start disable in this channel.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
• Stop the measuring function
• NCK reset
Switch control OFF - ON.
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.
- Channel not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
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 modify-
ing 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
