Cyclic Correction - ABB ACSM1 Manual

62.13 PRESET POSITION
Defines the preset position.
The unit depends on parameter
-32768...32768
Firmware block:

CYCLIC CORRECTION

(64)
This block
• selects the cyclic correction mode
• defines the source for the latching
command for position probe 1/2
• defines the reference position for
probe 1/2
• defines the maximum absolute
value for cyclic correction.
When the probe latching conditions
are fulfilled, the encoder module
saves the encoder position (to signal
4.03 PROBE1 POS MEAS or 4.04
PROBE2 POS MEAS).
62.14 CYCLIC CORR MODE
Selects the cyclic correction mode.
(0) Disabled
(1) Cor Act Pos
(2) Cor Mas Ref
(3) 1 Probe Dist
(4) 2 Probe Dist
(5) Cor M/F Dist
62.15 TRIG PROBE1
Defines the position data source and triggering command used for probe 1 latching. When the
triggering condition is fulfilled, the position received from the selected data source is set as probe 1
position.
In case the triggering condition is dependent on the zero pulse, the probe is latched upon the rising
edge of the zero pulse. The source of the zero pulse is defined by parameter
SOURCE 1.
