Figure 5.13 Wiring for reference coupling via clock signal 0-10 kHz
Note: The clock cables must be shielded. The shield must be
grounded over a wide area on one side.
Explanatory notes
• By way of the digital input ISD01 the reference of the device can
be specified with a clock signal of 0-10 kHz. The function selector
211-FIS01 must be set to INCLK.
• A clock signal proportional to the output frequency of the device can
be delivered at OSD01. The transmission ratio is adjustable in
increments of 2
n
from 1x to 128x, and is limited to the switching
frequency of the power stage (parameter 690-PMFS). The function
selector 241-FOS01 must be set to OCLK.
