The SIMODRIVE 611 D/ 611D signals the PLC that the speed actual value nact is less than the
minimum speed (n
min
).
The minimum speed is defined using the machine data:
MD1418 $MD_SPEED_THRESHOLD_MIN
.
Signal state 0 or
edge change
1 → 0
The speed actual value is higher than the minimum speed.
Corresponding to .... MD1418 $MD_SPEED_THRESHOLD_MIN (minimum speed (n

The 611D/ 611U signals the PLC that the speed actual value n
act
is less than the threshold speed
(n
x
).
The threshold speed is defined using the machine data:
MD1417 $MD_SPEED_THRESHOLD_X
.
Signal state 0 or

1 → 0
The speed actual value is higher than the threshold speed.
Corresponding to .... MD1417 $MD_SPEED_THRESHOLD_X (threshold speed (n
