act
Edge evaluation: No
Signal state 1 The actual speed value is at least the parameterized time (switch-on delay n_act = n_set, p2167)
within the tolerance band around the speed setpoint (speed threshold value 4, p2163).
Signal state 0 The actual speed value is outside the tolerance band around the speed setpoint (speed threshold
value 4, p2163).

DBX94.7 Variable signaling function
Edge evaluation: No
Signal state 1 The parameterized drive variable has exceeded the specified threshold value, including hysteresis.
Signal state 0 The parameterized drive variable has fallen below the specified threshold value, including hysteresis.
Remark Using the "Variable signaling" function, BICO interconnections and parameters which have the at‐
tribute traceable can be monitored in the drive.

DBX95.7 Warning of warning class C is pending
Edge evaluation: No
Signal state 1 The drive signals that a warning of warning class C is pending.
Signal state 0 The drive signals that no warning of warning class C is pending.
Remark In the drive, a warning is the response to a detected potential or expected fault condition that does
not cause the drive to switch off and does not have to be acknowledged.

DBX130.0 -
Motor/drive data set: Formatting interface
DBX21.4
Edge evaluation: No
Meaning The formatting interface is used to set which bits of the request and display interface are used to
address the motor data sets (MDS) and which are used to address the drive data sets (DDS):
Corresponding to ... DB31, ... DBX21.0 - 4 (motor/drive data set: request interface)
