Signal status, signal description
1 Operating Condition
Ready
0 OFF 3
Deceleration along the current limit, power disconnected
from the motor, tracking operation, power–on inhibit
1 Enable operation
Ready
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 An edge change may only be realized if bit 12 of the status
