Notes on the telegram structure
● Parameter p0978 contains the drive objects that use cyclic PZD exchange. All drive
objects after the first entry with "0" do not participate in the cyclic exchange.
● If the value 255 is written to p0978, this drive object is visible to the PROFIdrive controller
and empty (without actual process data exchange). This permits cyclic communication of
a PROFIdrive controller in the following cases:
– With unchanged configuration to drive units that have a different number of drive
objects.
– With deactivated drive objects, without having to change the project
● The following must apply to ensure conformity with the PROFIdrive profile:
– Interconnect PZD receive word 1 as control word 1 (STW1).
– Interconnect PZD send word 1 as status word 1 (ZSW1).
(For PZD1, the WORD format should be used)
● One PZD = one word.
● Only one of the interconnection parameters (p2051 or p2061) can have the value ≠ 0 for
a PZD word. The reason for this is that the assignment of word and double word overlap,
and various data cannot be simultaneously transferred on a PZD.
