(2) In this example the logic inputs LIx are wired as "sink", but can also be wired as "source int" or "source ext
(3) (1) Mains choke (if used)
(4) Standard coaxial cable type RG174/U in accordance with MIL-C17 or KX3B according to NF C 93-550, outer diameter 2.54 mm, maximum length 15 m.
The cable shield must be grounded.
(5) Use the cable ends DZ5CE020 (yellow) at the connector wires to the inputs PWR and +24
On activation of the stop command, the deceleration of the motor controlled by the inverter is first requested. Then
after a delay corresponding with the ramp-down time the safety function "power removal" is activated.
