Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The drive 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 The speed actual value is higher than the minimum speed.
Corresponding to ... MD1418 $MD_SPEED_THRESHOLD_MIN (minimum speed (n

))

Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The drive signals to 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 The speed actual value is higher than the threshold speed.
Corresponding to ... MD1417 $MD_SPEED_THRESHOLD_X (threshold speed (n

DBX94.6
n
act
= n
set
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The drive signals the PLC that after a new speed setpoint has been entered, the speed actual value
n
act
has reached the speed tolerance bandwidth:
MD1426 $MD_SPEED_DES_EQ_ACT_TOL (tolerance bandwidth for n
set
= n
act
signal)
and has remained within this tolerance bandwidth for at least the time defined using machine data:
MD1427 $MD_SPEED_DES_EQ_ACT_DELAY (delay time for n
set
= n
act
signal)
(refer to the diagram).
If the speed actual value then leaves the tolerance bandwidth, then contrary to the signal "ramp-up
completed", the interface signal:
DB31, ... DBX94.6 (n
act
= n
set
)
is set to 0.
