default value Description
2102 0 Total
resolution
u32, rw 0x1000000 Total resolution of the encoder
This parameter is used to set the
requested total resolution� The parameter
must not exceed the physical measuring
range of the encoder� The total resolution
and the resolution per revolution must be
entered using the following formula:
GA = (PGA x AU) / PAU
PGA
total physical resolution of the encoder
(see type label)
PAU
physical resolution per revolution of the
enocder (see type label)
GA
total resolution (customer-specific)
AU
resolution per revolution (customer-
specific)
If the requested total resolution is lower
than the total physical resolution, the total
resolution parameter must be a multiple of
the physical resolution per revolution�
2103 0 Preset value u32, rw 0 The preset value is a position value which
is to be indicated at a certain physical
position of the axis� The preset value must
not exceed the total physical resolution to
avoid runtime errors�
2104 0 Limit switch,
min�
u32, rw 0 Two position vaues can be programmed as
limit switch positions� When one of these
values has been reached, one of the 32-bit
position values is set� Both values must not
exceed the total physical resolution of the
encoder to avoid runtime errors�
The limit switch (min) sets bit 30 = 1 with the next telegram transmitted when the set position value
has been reached or fallen below�
