RS 485, Serial communication.
70
1
Frame for terminals 67, 68 and 69.
Normally this terminal is not to be used.
1. The terminals are not valid for DeviceNet/CANopen.
See also the DeviceNet manual, MG.90.BX.YY for fur-
ther details.
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)
NB!
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.
Switches 1-4
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 frequency converter is located
as the first or last unit in the bus SYSTEM, switches 1
and 2 must be ON. On the remaining frequency con-
verters, switches 1 and 2 must be OFF.
Switches 3 and 4 are not applied.
VLT Software Dialog
