Parameters 259
Defines which message types reset the timeout counter for
detecting an EFB communication loss.
Changes to this parameter take effect after the control unit is
rebooted or the new settings validated by parameter

.
Any message
Any message addressed to the drive resets the timeout.
1
Cw / Ref1 / Ref2
A write of the control word or a reference from the fieldbus
resets the timeout.
2
Sets a timeout for EFB communication. If a communication
break lasts longer than the timeout, the action specified by
parameter
Changes to this parameter take effect after the control unit is
rebooted or the new settings validated by parameter
Note:
There is a 30-second boot-up delay immediately after
power-up. During the delay, the communication break
monitoring is disabled (but communication itself can be
active).

3.0 s
0.0 … 6000.0 s
EFB communication timeout.
1 = 1
Defines a minimum response delay in addition to any fixed
delay imposed by the protocol.

rebooted or the new settings validated by parameter
0 ms
0…65535 ms
Minimum response delay.
1 = 1
Displays the raw (unmodified) control word sent by the
Modbus controller to the drive. For debugging purposes.
This parameter is read-only.
-
0000h…FFFFh
Control word sent by Modbus controller to the drive.
1 = 1
Displays the raw (unmodified) status word sent by the drive to
the Modbus controller. For debugging purposes.
This parameter is read-only.
-
0000h…FFFFh
Status word sent by the drive to the Modbus controller.
1 = 1
Defines the control profile used by the protocol.
ABB Drives
ABB Drives profile (with a 16-bit control word) with registers in
the classic format for backward compatibility.
0
Transparent
Transparent profile (16-bit or 32-bit control word) with
registers in the classic format.
2
Selects the type and scaling of reference 1 received through
the embedded fieldbus interface.
The scaled reference is displayed by
.
Auto
Type and scaling are chosen automatically according to which
reference chain (see settings
) the
incoming reference is connected to. If the reference is not
connected to any chain, no scaling is applied (as with setting
0
Transparent
No scaling is applied.
