Long Parameter Menu
2.07 Comm Fault Mode
Selection of the desired operating response to a
communication failure:
0 = Ramp
Motor is decelerated in accord. to a ramp (5.10)
1 = Torque Lim
Motor is decelerated in accord. to the torque limit
2 = Coast
fault message and shutdown of drive
Response time of deceleration by Ramp or Torque
depends on optimization of speed regulator.

2.08 Comm Fault Time
Tolerance time for fault messages in the case of
communication faults. Time between two successive
messages. If (2.08) = 0.00 s ignore, and continue
with ongoing operation
0.00 10.00 5.00 s
x
2.09 Start Mode
Selection of the desired operating response to a
start command, while drive is still rotating, braking
or coasting
0 = Start From 0: wait until motor has reached zero
speed, then re-start
1 = Flying start: Start with the motor actual speed

2.10 DDCS Node Addr
Internal DDCS address between DCS400 and the
field bus adapter.
1 254 1 integer
x
2.11 DDCS Baud Rate
Transmission speed between DCS400 and field bus
adapter.
0 = 8 Mbaud
1 = 4 Mbaud
2 = 2 Mbaud
3 = 1 Mbaud
0 3 1 integer
x
2.12 PTC Mode
The response of the drive when the thermistor trips
is selectable:
0 = Disabled no PTC evaluation
1 = Alarm generates
Alarm A05
only
2 = Fault generates
Fault
F08
and switches
the drive off.
A thermistor in the motor (PTC element) can be
evaluated via the analog input
AI2
in DCS400.
Thermistor connection to
X2:3
and
X2:4.
Connect
X2:4
with
X2:5 (0V).
Insert the jumper
S1:5-6
(22k to 10V).
If PTC is allocated to
AI2
this input will not be
available to other functions any more. If
AI2
is
parameterized as a reference source (macro 1, 2, 4,
5, 7), the Alarm
Parameter Conflict (A16)
will be
generated
.
Then set parameter
Torque Ref Sel
(3.15) = Const Zero

2.13 Fan Delay
Adjustable time for signal „
Fan On
“. Will be started
when the drive is switched off (ON=0). If motor or
DCS400 is overheated, Fan Delay will be started
after cooling.
