DI2 Digital input DI2 ( 10.02 DI delayed status , bit 1). 4
DI3 Digital input DI3 ( 10.02 DI delayed status , bit 2). 5
DI4 Digital input DI4 ( 10.02 DI delayed status , bit 3). 6
DI5 Digital input DI5 ( 10.02 DI delayed status , bit 4). 7
DI6 Digital input DI6 ( 10.02 DI delayed status , bit 5). 8
DIO1 Digital input/output DIO1 ( 11.02 DIO delayed status , bit 0). 11
DIO2 Digital input/output DIO2 ( 11.02 DIO delayed status , bit 1). 12
EFB MCW bit 11 Control word bit 11 received through the embedded fieldbus
interface. 32
Other [bit] Source selection (see Terms and abbreviations on page 148 ). -
19.12 Ext1 control mode Selects the operating mode for external control location
EXT1. Speed
Zero None. 1
Speed Speed control. The torque reference used is 25.01 Torque
reference speed control (output of the speed reference
chain).
2
Torque Torque control. The torque reference used is 26.74 Torque ref
ramp out (output of the torque reference chain).
3
Minimum Combination of selections Speed and Torque : the torque
selector compares the speed controller output ( 25.01 Torque
reference speed control ) and the torque reference ( 26.74
Torque ref ramp out ) 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 Speed and Torque : the torque
selector compares the speed controller output ( 25.01 Torque
reference speed control ) and the torque reference ( 26.74
Torque ref ramp out ) 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 Combination of selections Speed and Torque : Torque selector
adds the speed reference chain output to the torque
reference chain output.
6
19.14 Ext2 control mode Selects the operating mode for external control location
EXT2.
For the selections, see parameter
19.12 Ext1 control mode .
Speed
19.16 Local control mode Selects the operating mode for local control. Speed
Speed Speed control. The torque reference used is 25.01 Torque
reference speed control (output of the speed reference
chain).
0
Torque Torque control. The torque reference used is 26.74 Torque ref
ramp out (output of the torque reference chain).
