Intermediate circuit DC undervoltage trip limit.
The higher range limit is determined by Par.
30.11 DC OVERVOLT TRIP. When the setting
of this parameter is changed, the
corresponding lower range limit of Par. 30.11
DC OVERVOLT TRIP will also change. This
parameter also determines DC voltage check
limit during charging.

COMMUNICATION
MODULE
This group defines the communication parameters for a fieldbus adapter module. The
parameter names are copied from the module when it is installed and its connection to the
drive is activated with Parameter 98.02 COMM MODULE. See the module manual.

CH0 NODE ADDR
R
1
1...125
Node address for channel CH0. When
using the AC 80 system, the address must
be 1. In other control systems, node
address is set according to the
application.

1...15
DDCS channel CH0 intensity control for
transmission LEDs. This parameter can
be used in special cases to optimise the
communication performance in the link.

Channel CH0 communication speed. This
parameter must be set to 4 Mbits/s, when
FCI communication module is used.
Otherwise overriding system
automatically sets the communication
speed.
70.04
CH0 TIMEOUT
R
100 ms
0...60000 ms
The delay time before a communication
break fault is indicated. The time count
starts when the link does not update the
message. During the time elapsing, CH0
TIMEOUT warning is set by 9.12 SUPPLY
ALARM WORD bit 0. When the value of
Par. 70.04 is zero, timeout is not
monitored and CH0 COM LOST fault is
not indicated regardless of the value of
Par. 70.05.
