Pos Feedback - ABB ACSM1 Manual

Firmware block:

POS FEEDBACK

(60)
This block
• selects the source for measured
actual position value (encoder 1,
encoder 2 or estimated position)
• selects whether positioning is
executed along linear or rollover
axis
• configures the load encoder gear
function
• selects the unit and scaling for the
position parameters
• selects the integer scaling of a
position value
• defines how many bits are used for
position count within one revolution
• defines the minimum and maximum
position limits
• defines the position threshold
supervision limit
• shows actual position of the
encoder, scaled actual position of
encoder 2 and filtered actual speed
of the load.

FW block: POS FEEDBACK
Encoder 1. Inverted gear ratio is considered when the position control
output (speed reference) is produced.
Encoder 2. Inverted gear ratio is considered when the position control
output (speed reference) is produced.
Estimated position. Inverted gear ratio is considered when the position
control output (speed reference) is produced. See also section
Position estimation on page 60.
FW block: POS FEEDBACK
Linear motion. Positioning is between minimum position
MINIMUM POS and maximum position
Rotating motion. Positioning is between 0 and 1 revolutions, ie, after
360°, the position calculation starts from 0° again.
