11.5 Synchronization input
•
opto-isolated input
•
input signals between 5V and 30 V
•
for NPN- or PNP-open collector, push-pull, or TTL encoder output
•
Scatec FLDM 170G…… (push-pull output) accepts an A/B-channel encoder
•
Scatec FLDM 170C…… (opto-isolated output) accepts an A-channel encoder only.
•
synchronization input signal levels logical high: > 3.8 V (> 2.2 mA)
logical low: < 1.8 V (< 0.7 mA)
•
frequency max. 50 kHz
•
reverse polarity: protected
11.6 Wiring instructions
In order to achieve optimum protection of the Scatec against electromagnetic interference
•
use shielded cables
•
keep the ground impedance sufficiently low
We suggest the following two grounding schemes:
Version 1
•
Scatec housing is grounded (use teeth lock washers when
mounting the Sactec).
•
Cable shield not grounded at the controller end.
•
Cable shield properly attached to the connector plugging
into the Scatec.
