Using a DC Contactor and an Inverting Fault Device
DC Contactor Configuration
1. Set parameter 1391[ContactorControl] to "Contactor" (default value).
2. Set one [Relay Out x Sel] parameter and one [Digital Inx Sel] parameter
to "Contactor" (default value for parameters 1392 [Relay Out 1 Sel] and
140 [Digital In8 Sel]).
3. Connect the DC contactor auxiliary (status) contact to a digital input.
4. Set the corresponding [Digital Inx Sel] parameter (133-144) to 35 - “Fld
Weak En”.
5. Set the corresponding [Inversion In x] parameter (1276-1283 or
1387-1390) to 1 - “Enabled”.
Inverting Fault Device Configuration
1. Connect the inverting fault device contact to a digital input.
2. Set the corresponding [Digital Inx Sel] parameter (133-144) to 14 - "Aux
Fault".
3. Set the corresponding [Inversion In x] parameter (1276-1283 or
1387-1390) to 1 - “Enabled”.
Using a DC Contactor, a Dynamic Brake and an Inverting Fault Device
DC Contactor and Dynamic Brake Configuration
1. Set parameter 1391[ContactorControl] to "Contactor+DB".
2. Set one [Relay Out x Sel] parameter (1392 [Relay Out 1 Sel] or 629
[Relay Out 2 Sel]) to "Contactor" and the other relay output to
"ContactorDB".
3. Set one [Digital Inx Sel] parameter to "Contactor" (default value for
parameter 140 [Digital In8 Sel]).
4. Connect the DC contactor auxiliary (status) contact to a second digital
input.
5. Set the corresponding second [Digital Inx Sel] parameter (133-144) to
"Fld Weak En".
6. Set the corresponding [Inversion In x] parameter (1276-1283 or
1387-1390) for the second digital input to "Enabled".
