18.2 Displaying the Service overview
Ramp-up function completed
The status display of the drive as to whether the ramp-up has been completed corresponds
to the interface signal:
DB31, ... DBX94.2 "Ramp-up completed".
Status
1
0
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:
DB31, ... DBX94.3 "|M
Status
1
0
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:
DB31, ... DBX94.4 "|n
Status
1
0
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:
DB31, ... DBX94.5 "|n
Status

Meaning
The actual speed value has reached the speed tolerance band specified via
p2164 after a new speed setpoint specification and has not left the band for
the duration of p2166.
The ramp-up procedure is still active after the speed setpoint has been
changed.
| < M ".
d dx
Meaning
The current torque utilization lies below the torque utilization threshold set in
p2194. The drive signals the PLC that the torque setpoint |M
ceed the threshold torque M
The torque setpoint |M | is larger than the threshold torque M

Meaning
The actual speed value |n
set in p2161.
The actual speed value is greater than the threshold minimum speed.

act x
Meaning
The actual speed value |n
The actual speed value is greater than the set threshold speed.
