Process data of power section
Process Data Description
Bits 8 – 15 are assigned depending on the value of bit 5 according to the following table:
Actual speed
Set to SPEED, the power section returns the current actual speed in "rpm" to the higher-
level automation system. The exact actual speed can only be sent back when the power
section can determine the actual motor speed using speed feedback. For applications
with slip compensation, the deviation from the real motor speed solely depends on the
accuracy of the slip compensation set by the user.
Coding: 1 digit = 0.2 rpm
Active current
By assigning a process input word ACTIVE CURRENT, the power section provides the
actual active current value in "% I
N
" to the higher-level automation system.
Coding: 1 digit = 0.1 % I
N
8.5.2

The process output and input data words of the "Bus positioning" application module are
assigned as follows:
PO:
• PO1: Control word 2
• PO2: Setpoint speed
• PO3: Target position
PI:
• PI1: Status word
• PI2: Actual velocity
• PI3: Actual position
