5 General concepts
Holding torque in the Switched on state
Ex works, no holding torque is built up in the Switched on state. If a holding torque is already needed in
this state, the value "1" must be written in 3212
h
:01
h
.
Note
If the Holding torque in the switched on state option is active, changing the operating mode may
cause the motor to jerk.
Statusword
Listed in the following table are the bit masks that break down the state of the controller.

After switching on and successfully completing the self-test, the controller reaches the Switch on
disabled state.
Operating mode
h
) does not become active until the Operation enabled state. The actually
active operating mode is displayed in 6061
h
.
The operating mode can only be set or changed in the following states (see states enclosed in a
dashed border in the diagram):
•
Switch on disabled
•
Ready to switch on
•
Switched on
It is not possible to change the operating mode in running operation (Operation enabled). The Fault
state is exited if bit 7 in object 6040
(controlword) is set from "0" to "1" (rising edge).
Note
If an unrecoverable error occurs, the controller changes to the Not ready to switch on state and
remains there.
5.2.2 Behavior upon exiting the Operation enabled state
Halt motion reactions
Various halt motion reactions can be programmed upon exiting the Operation enabled state.
The following graphic shows an overview of the halt motion reactions.
