Note
For double words, two PZD must be read in succession. To do this, read in a 32 bit setpoint,
which is on PZD
2 + PZD 3 of the telegram of node 2. Emulate this setpoint on
PZD
2 + PZD 3 of node 1:
p8872[1]
= 2, p8870[1] = 2, p8872[2] = 2, p8870[2] = 3
Activation
To activate SINAMICS Link connections, perform a POWER ON for all nodes. The
assignments of p2051[x]/2061[2x] and the links of the read parameters r2050[x]/2060[2x]
can be changed without a POWER ON.
Settings for chassis units with rated pulse frequency 1.25 kHz
For the following chassis units with a rated pulse frequency of 1.25 kHz, in addition
parameter p0115[0] must be set from 400 µs to 250 µs or 500 µs:
● 3 AC 380 to 480 V: All chassis units with rated output current I
N
≥ 605 A
● 3 AC 500 to 600 V: All chassis units
● 3 AC 660 to 690 V: All chassis units
Generally, the following conditions must be met:
1. r2064[1] bus cycle time (Tdp) must be an integer multiple of p0115[0] (current controller
clock cycle).
2. r2064[2] master cycle time (Tmapc) must be an integer multiple of p0115[1] (speed
controller cycle).
