- Alarm display.
- NC Stop on alarm.
- Channel not ready.
• Stop the measuring function
• NCK reset
Switch control OFF - ON.
Axis %1 drive %2 direct feedback recognized
%1 = NC axis number
%2 = Drive number
The current rotor position and the position information read out by the encoder on ramp-
up were compared with each other and a deviation of more than 45 degrees was found.
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.

• The deviation points to a local contamination of the encoder or an erroneous or loose
encoder assembly. The encoder must be examined accordingly.
Operation may commence again only after successful error correction as there is a risk of
uncontrollable movements!
• 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 heat-
sink. 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.
