0 Inhibit operation
Power disconnected from the motor, motor coasts down,
”operation inhibited” status
1 Operating condition for program
The signal must be continuously present in order to execute
a traversing task.
0 Stop
Deceleration along the current limit.
The motor remains stationary with the holding torque.
The actual traversing task is rejected.
1 Operating condition for program
The signal must be continuously present in order to execute
a traversing task.
0 Intermediate stop
The drive brakes from an active traversing task along the
ramp to n = 0 and then remains stationary with the holding
torque.
The traversing task is not rejected.
For a change to bit 5 = 1, the traversing task is continued.
1/0 Each edge enables a traversing task or a new setpoint
(toggle bit).
An edge change may only be realized if bit 12 of the status
0/1
word is used to acknowledge that the previous traversing
task was accepted.
A program start is valid as a traversing task.
1 Acknowledge faults (0/1 edge)

If operation is enabled and positioning is not active ––> the
drive traverses closed–loop speed controlled with jogging
