Description

No.
- / uint32
Together with
87.16 Master axis modulo denominator
defines the rollover axis configuration.
When this parameter is set to 0, the master axis is linear
and limited by the range of 32 bits of increments of the
holding variable.
If this parameter is not set to 0, the ratio of the
numerator and denominator defines the range of the
rollover axis measured in revolutions of the master
reference source.
Note that master input increments are converted to
revolutions based on

Disable / uint32
Forces (or selects a signal that forces) the master axis
to linear even if parameter
is non-zero, ie. if the
master axis is defined as rollover. This parameter can
be used to convert the input from a rollover source to
a linear reference for the controlled axis.
A typical application is an algorithm (eg. flying shear)
that needs a linear master axis but the master reference
is received as circular via the D2D channel.
Force linear master

0
The modulo numerator determines if the master axis
is linear or rollover.
Disable
1
Master axis is forced to linear.

None / uint16
Forces (or selects a signal that forces) the master axis
to linear even if parameter
is non-zero, ie. if the
master axis is defined as rollover. This parameter can
be used to convert the input from a rollover source to
a linear reference for the controlled axis.

0
No external encoder in use.
None
1
External encoder source is encoder 1 position.
Encoder 1
2
External encoder source is encoder 2 position.
Encoder 2
Positive / uint16
Defines the direction of the external encoder to be
tracked internally. The parameter changes the delta
increment coming from the master feedback sensor.
External encoder
direction
87.21
0
Tracking direction not inverted.
Positive
1
Tracking direction inverted.
Negative
- / uint32
Defines the number of increments that span a modulo
range for the external encoder position. If this setting
is greater than zero, the master axis position is always
restored within the defined modulo range.
