Parameters 195
DI1
Digital input DI1 (
, bit 0).
3
DI2
Digital input DI2 (
, bit 1).
4
DI3
Digital input DI3 (
, bit 2).
5
DI4
Digital input DI4 (
, bit 3).
6
DI5
Digital input DI5 (
, bit 4).
7
DI6
Digital input DI6 (
, bit 5).
8
DIO1
Digital input/output DIO1 (
, bit 0).
11
DIO2
Digital input/output DIO2 (
, bit 1).
12
EFB MCW bit 11
Control word bit 11 received through the embedded fieldbus
interface.
32
Source selection (see
). -
Selects the operating mode for external control location EXT1.
Zero
None.
1
Speed
Speed control. The torque reference used is
(output of the speed reference chain).
2
Torque
Torque control. The torque reference used is
(output of the torque reference chain).
3
Minimum
and
: the torque
selector compares the speed controller output (
) and the torque reference (
) and selects the smaller of the two.
If speed error becomes negative, the drive follows the speed
controller output until speed error becomes positive again.
This prevents the drive from accelerating uncontrollably if the
load is lost in torque control.
4
Maximum
Combination of selections
and
: the torque
selector compares the speed controller output (
) and the torque reference (
) and selects the greater of the two.
If speed error becomes positive, the drive follows the speed
controller output until speed error becomes negative again.
This prevents the drive from accelerating uncontrollably if the
load is lost in torque control.
5
Add
: Torque selector
adds the speed reference chain output to the torque reference
chain output.
6
Voltage
(Type BCU control units only) DC voltage control. The torque
reference used is
(output
of the DC voltage reference chain).
7
Selects the operating mode for external control location EXT2.
For the selections, see parameter
Selects the operating mode for local control.
Speed
Speed control. The torque reference used is
(output of the speed reference chain).
0
Torque
Torque control. The torque reference used is
(output of the torque reference chain).
1
Enables/disables local control (start and stop buttons on the
control panel, and the local controls on the PC tool).
WARNING!
Before disabling local control, ensure that
the control panel is not needed for stopping the drive.
No.
