Signal and parameter list
Chapter overview
This chapter describes all signals and parameters of the DCS550.
Signal groups list
Signals are measured and calculated actual values of the drive. This includes the control-, status-, limit-, fault-
and alarm words. The drive’s signals are available in groups 1 to 9. None of the values inside these groups is
stored in the flash and thus volatile.
Note:
Signals in group 7 can be written to by means of DWL, DCS Control Panel, AP or overriding control.
The following table gives an overview of all signal groups:

Sample of signals
All signals are read-only. However, the overriding control can write to the control words, but it only affects the
RAM.
Min., max., def.:
Minimum, maximum and default values are not valid for groups 1 to 9.
Unit:
Shows the physical unit of a signal, if applicable. The unit is displayed in the DCS Control Panel and DWL.
Group.Index:
Signal and parameter numbers consists of group number and its index.
Integer Scaling:
Communication between the drive and the overriding control uses 16-bit integer values. The overriding control
has to use the information given in integer scaling to read the value of the signal properly.
Example1:
If the overriding control reads MotTorq (1.08) 100 corresponds to 1 % torque.
Example2:
If the overriding control reads SpeedRefUsed (2.17) 20,000 equals the speed (in rpm) shown in
SpeedScaleAct (2.29).
