4.2.3 Conditions when setting the motor protection
Ensure that the following conditions are met when setting the motor protec-
tion or when displaying the set value:
•
the device has a voltage supply (SWD and voltage to the terminals
1/L1, 3/L2, 5/L3).
•
There are no errors.
•
There is no start signal on the terminals ON, L or R.
The setting of the motor protection is part of the acyclical data
(
section 3.4.2.2, “Acyclicaloutput data”, page 30) and takes place in the
PLC program or using the SWD Assist software. A differentiation is made
between motor protection 1 and motor protection 2, where the value for
motor protection 2 must be lower than or equal to that of motor protection 1.
Having sent the setting to the motor starter, the LED
PWR
flashes. The other
four LEDs show the set value according to table 11 below. In order for the
set value to be adopted, when setting the motor protection 1, the SET button
must be pressed; this is not necessary when setting the motor protection 2.
After this, the
PWR
LED lights up permanently.
When using the following SWD gateways, the setting of the motor protec-
tion is carried out using the SWD Assist software:
•
EU5C-SWD-EIP-MODTCP (Ethernet IP and Modbus TCP)
•
EU5C-SWD-POWERLINK (Powerlink)
