■
Drivecom 21 objects.
The VLT®5000 supports 9 Drivecom specific objects.
The objects can be access by PCP communication.
4 of these objects can also be accessed as process
data.
Object 6040
H
, Control Word:
This object is the same as the Drivecom Control Word
Object 6041
H
, Status Word:
This object is the same as the Drivecom status word .
Object 6042
H
, Nominal-Speed-Value :
This object is the same as the Bus reference (MRV).
Object 6043
H
, Reference-Speed-Variable:
This is the reference after the Ramp. This value is read
only (-32768 to 32767) .
Object 6044
H
, Actual-Speed-Value:
This object is the same as the Actual output RPM.
The value of the actual output RPM of the Motor, is
transmitted in the form of a 16-bit word. The value is
transmitted as a whole number (-32768 to 32767).
Object 6046
H
, Speed-min-max-amount:
The Speed-Min-Max-Amount Object is composed of
the Speed-Min-Amount and Speed-Max-Amount sub
objects. These subobjects have no unit and have val-
ues within a range from 0 to 4 294 967 295 (unsigned
32).The Interbus Option translates these two indexes
into the VLT®5000 parameter 204 and 205. Based on
Parameter 106 (Motor Norminal Speed) the option
calculation new values for P.204 & P.205.
Object 6048
H
, Speed-Acceleration:
The Speed-Acceleration object specifies the slope of
the acceleration ramp (
α
) The object has 2 indexes
where: Index 1, is the Delta-Speed (unsigned 32) and
index 2 is Delta-Time (unsigned 16). If Delta-Time is
set to 0 (zero) the ramp is disabled. The VLT®5000
Interbus Option translate these two values into the
VLT®5000 parameters 106, Motor norminal speed
and parameter 207, ramp up time.
Object 6049
H
, Speed-Deceleration:
The Speed-deceleration object specifies the slope of
the deceleration ramp (
α
) The object has 2 indexes
where: Index 1, is the Delta-Speed (unsigned 32) and
index 2 is Delta-Time (unsigned 16). If Delta-Time is
set to 0 (zero) the ramp is disabled. The VLT®5000
Interbus Option translate these two values into the
VLT®5000 parameters 106, Motor norminal speed
and parameter 208, ramp down time.

The VLT®5000 will first activate the
changes when both indexes are written.
Since the VLT®5000 translates the two
indexes into VLT®5000 paramters, the
value written to Object 6048
H
may be dif-
ferent from a following read, but the slope
(
α
) is correct !

Object 603F
H
, Malfunction:
This is the errors reported back to the Master system.
A detailed list is on the next page.
Object 6052
H
, Normial-Percentage :
This object is the Normial setpoint in %. . The value is
transmitted as a whole number ±100% = ±4000
H.
This value is read only.
Object 6054
H
, Actual-Percentage :
This object is the actual speed of the motor . The
value is transmitted as a whole number ±100% =
±4000
