DETAILED PARAMETER DESCRIPTION
Figure 6.9 - Operating mode of the RL2 for the DC braking
6.4.8 - P53 - Program-
ming of the Dig-
ital Input 2
Enable the digital input 2 (terminal X2:2) to operate
according to described codes:
OFF = without function
1 - Error Resetit reset an error status every time the DI2
input is at +24Vdc (X2:5).
2 - External Error = can be used as additional load protec-
tion. It acts when the input is open.
Ex.: thermal protection for the motor by means of dry
contact (without voltage) of a protection relay (thermo-
stat).
3 - General Enabling = X2:2 must be connected to +24Vdc
(X2:5) for the Soft-Starter to operate. If it is not connected,
the SCRs firing pulses are disabled.
NOTE!
1) Before starting programming, make all needed external
connections.
2) DC-Braking cannot be performed when the Soft-Starter is con-
nected within the motor delta connection (P28=ON).
