Torque lower than threshold setting
The status display of the drive as to whether the threshold torque has been undershot
corresponds to the interface signal:
DB390x, ... DBX4002.3 "|M
d
| < M
dx
".
Status Meaning Display
1 The current torque utilization lies below the torque utilization threshold set in
p2194. The drive signals the PLC that the torque setpoint |M
d
| does not ex‐
ceed the threshold torque M
dx
.
Yes
0 The torque setpoint |M
d
| is larger than the threshold torque M
dx
. This signal
can be used to determine whether the motor is overloaded.
No
Speed lower than minimum setting
The status display of the drive as to whether the minimum speed has been undershot
corresponds to the interface signal:
DB390x, ... DBX4002.4 "|n
act
| < n
min
".
Status Meaning Display
1 The actual speed value |n
act
| is less than the threshold minimum speed n
min
set in p2161.
Yes
0 The actual speed value is greater than the threshold minimum speed. No
Speed lower than threshold setting
The status display of the drive as to whether the threshold speed has been undershot
corresponds to the interface signal:
DB390x, ... DBX4002.5 "|n
act
| < n
x
".
Status Meaning Display
1 The actual speed value |n
act
| is less than
the threshold speed n
x
set in p2155. Yes
0 The actual speed value is greater than the set threshold speed. No
Actual speed = set speed
The
status
display
of
the drive as to whether the actual speed value matches the speed setpoint
corresponds to the interface signal:
DB390x, ... DBX4002.6 "|n
act
| < n
set
".
Status Meaning Display
1 The speed deviation between the setpoint and actual value is within the tol‐
erance specified in p2163.
Yes
0 The speed deviation between setpoint and actual value is outside the speci‐
fied tolerance.
No
