CUT-OFF TIMEOUT
STATUS
DATA SET OFFSET
NO. OF DATA SETS
5-4
This parameter defines the time after which the NCAN-02 makes a
self-reset and thus stops communicating (with the drive and the
master) in case the PDO communication between the NCAN-02 and
the master fails. Cut-off supervision is activated upon a successful
receipt of a PDO, i.e. this parameter has no effect if no messaging has
taken place.
The actual timeout in seconds is the value of this parameter (1 ... 255)
divided by 10. Setting the parameter to 0 disables cut-off supervision.
0 (disabled); 1 ... 255
This parameter indicates the status of the NCAN-02 module.
Value
(0) SELF TEST
(1) RX Q OVERRUN
(2) CAN OVERRUN
(3) BUS OFF
(4) ERROR SET
(5) ERROR RESET
(6) TX Q OVERRUN
(7) DISCONNECTED Node state changed to DISCONNECTED.
(8) STARTED
(9) STOPPED
(10) G FAILS
(11) PRE-OPERAT.
(12) RESET COMM.
(13) RESET NODE
This parameter selects the number of the first data set to be used for
fieldbus communication. By default, the value of this parameter is FBA
D SET 1, denoting that data sets from no. 1 onwards are used for
communication with the drive. However, some drives reserve these
data sets for other use, and thus it may be necessary to use other data
sets. Setting this parameter to the value of FBA D SET 10 makes data
set 10 the first data set to be used for the communication between the
NCAN-02 and the drive.
FBA D SET 1; FBA D SET 10
This parameter defines the number of data sets and activated PDOs
sent in each direction.
1 ... 4
