Rules For Wiring The Drive-Cliq Interface - Siemens SINUMERIK 840D sl Commissioning Manual

Manual identification
Further identification methods:
● p3410 = 4 (identify and save controller setting with L adaptation)
An identification run for the total inductance and DC link capacitance is initiated when the
pulses are next enabled: Two measurement routines with different current magnitudes. The
determined data (r3411 and r3412) is entered into p3421 and p3422. At the same time, the
controllers are recalculated and the parameters for current controller adaptation are defined
(p3620, p3622). The parameters for the infeed module are then automatically stored in a
non-volatile memory. The infeed unit continues to operate without any interruption with the
new controller parameters.
● p3410 = 5 (resetting, saving ID and controller setting with L adaption)
The parameter values for line inductance and DC link capacitance are reset before the first
identification run:
p3421 = p0223 and p3422 = p0227
● p3410 = 6 (Setting, C-identifying and saving robust current controller)
For infeed units of the type Chassis 2, use p0220 ≥ 110 to select corresponding Active
Interface Modules of the Chassis 2 (AIM Chassis-2) design and start the automatic
controller setting with p3410 = 6. At the same time, the value of the DC link is determined in
a shortened measurement. All of the other controller parameters are already preset by
setting p3410 = 6.
– Advantage: For modified mains parameters (e.g. switchover to a different mains), no
– Disadvantage: Unlike identification over p3410 = 5, the automated controller setting
P3410 = 0 is automatically set when an identification routine is successfully completed.

Rules for wiring the DRIVE-CLiQ interface

Topology rules
When wiring components with DRIVE-CLiQ, the following rules apply: The rules are subdivided
into obligatory rules, which must be observed, and optional rules, which enable automatic
topology detection if they are adhered to.
Obligatory rules:
● A maximum of 198 DRIVE-CLiQ node components can be connected for each NCU.
● Up to 16 nodes can be connected to a DRIVE-CLiQ socket.
● A maximum of seven nodes can be connected in one row. A row is always considered from
the perspective of the closed-loop control module.
● Ring wiring is not permitted.
● Components must not be double-wired.
Optional rules:
