Table 45:
Reaction after a loss of communication
PNU 840.29952 = 0 or = 1 (Fire Mode)
Figure 35:
Fire mode
In fire mode, the variable frequency drive/variable speed starter will continue
to run with the last valid command word (bit 10 has the highest priority of all
bits in the command word).
The detected error is written to the error buffer, the error bit is set, the varia-
ble frequency drive/variable speed starter continues to run even if the error
bit is set and waits for a reset command to reset the error bit; a restart is not
required. The variable frequency drive/variable speed starter runs to the end
or communication returns with valid commands.

Action@Communication Loss
P-40 (DE1),
P-53 (DC1)
Device-dependent reaction after a “Communication
Loss” occurs.
The delay time after a loss of communication is set
using P-36.
0: No reaction, drive continues to run
1: Output warning; drive continues to run
2: Stop if ramp active
3: Quick stop
4: Coast stop (= factory setting)
