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.
