62.16 PROBE1 POS
Defines the reference position for position probe 1.
The unit depends on parameter
-32768...32768
62.17 TRIG PROBE2
Defines the position data source and triggering condition used for probe 2 latching. When the
triggering condition is fulfilled, the position received from the selected data source is set as probe 2
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 2.
For selections, see parameter
62.18 PROBE2 POS
Defines the reference position for position probe 2.
The unit depends on parameter
-32768...32768
62.19 MAX CORRECTION
Defines the maximum absolute value for cyclic correction. Example: If maximum value is set to 50
revolutions and the requested cyclic correction is 60 revolution, no correction is made.
The unit depends on parameter
0...32768
62.20 POS ACT OFFSET
Offsets all the position values used by the position system, effectively correcting the position and
revolution count signal received from the encoder. For example, this parameter can be used if a non-
zero position signal received from the encoder needs to be defined as the zero position for the
application.
For example, if this parameter is set to a value of -100, the absolute position of 100 revolutions as
measured by the encoder is interpreted as the zero position.
Notes:
• The offset takes effect upon the next power-up or when an encoder reconfiguration command is
given using parameter
• The offset will not be visible through any actual signal or other parameter.
