Automatic AssistedDrive

Function description
The automatic AssistedDrive system is composed of both the ImpulseDrive and
AssistedDrive detection systems.
On the one hand, ImpulseDrive is used to generate a corresponding drive order with a
normal drive profile. On the other hand, the drive order is canceled ("deenergized") with the
aid of AssistedDrive.
To do this, automatic AssistedDrive evaluates the edges of the IMPDRVIncr, IMPRDRVVelo
and ASDR signals.
The automatic AssistedDrive system can only be used with an active enable. The enabling
signal for the automatic AssistedDrive system (DCMD := 6) is an element of the DCMD
signal (see Table A-16 DCMD signal (Page 287)). This ensures the unambiguity of the active
drive order at all times.

Note
After the automatic AssistedDrive system has canceled a drive order on account of an
inadequate assisting force, ImpulseDrive detection becomes active again. However, the
ImpulseDrive lead time (p1220) must be taken into account. It directly affects the signal
chain of the automatic AssistedDrive system.
Note
Configuring ImpulseDrive and AssistedDrive detection directly affects the automatic
AssistedDrive system.
