Relay connection
See parameter 323 Relay output for programming of
relay output.
Nr.
01 - 02 1 - 2 make (normally open)
01 - 03
1 - 3 break (normally closed)
NOTE
Please note that the cable jacket for the
relay must cover the first row of control
card terminals - otherwise the galvanic
isolation (PELV) cannot be maintained.
Max. cable diameter: 4 mm. See drawing.
Profibus DIP switches setting
The dip switch is only on the control card with Profibus
DP communication. The switch position shown is the
factory setting. Switches 1 and 2 are used as cable
termination for the RS-485 interface. If the adjustable
frequency drive is located as the first or last (or only)
unit in the bus system, switches 1 and 2 must be ON.
On the remaining adjustable frequency drives,
switches 1 and 2 must be OFF. Switches 3 and 4 are
not applied.
