Speed lower than threshold setting
Status display of drive.
State 0: The actual speed value is greater than the threshold speed.
Status 1: The actual speed value is smaller than the threshold speed.
The threshold speed corresponds to machine datum:
MD1417 $MD_SPEED_THRESHOLD_X
(n
x
for 'n
actual
< n
x
' message).
Display corresponds to NST DB31, ... DBX94.5 ("|n
actual|
< n
x
").

Actual speed = set speed
Status display of drive.
The speed tolerance band corresponds to machine datum:
MD1426 $MD_SPEED_DES_EQ_ACT_TOL (tolerance band for 'n
set
-n
actual
' message).
Display corresponds to NST DB31, ... DBX94.6 ("|n
actual
|= n
set
").

Variable signal 1
Status display of 611D variable signaling function.
With the variable signaling function, any memory location can be monitored to see whether a definable threshold
is exceeded. In addition to the threshold, a tolerance band can be defined which is also taken into account when
scanning for violation of the threshold value. The signal can be combined with an ON delay or OFF delay time.
State 0: Threshold value not reached
State 1: Threshold value exceeded
Parameters for the variable signal function are set using the following 611D machine data:
State 0: The actual speed value is outside the speed tolerance band after a
new speed setpoint was defined.
State 1: The actual speed value has reached the speed tolerance band after a new
speed setpoint was defined.
