2 FAULTS AND ALARMS
2.1 FAULTS
In order to avoid dangerous situations and damages to the motor, converter, and other materials, the
protections of the CTW900 may actuate so that certain physical limits will not be exceeded.
In this regard, a fault is a condition that requires immediate stop of the converter so as to prevent possible
losses. When a fault occurs, the CTW900 is automatically disabled and cannot be restarted until the cause of
the fault is removed.
The actuation of the faults occurs as follows:
■
The converter is disabled by removing the firing from the armature;
■
The converter status becomes “Fault” and it is displayed in the status word (P0680);
■
The “Status” LED flashes red;
■
The fault code is displayed on the keypad (HMI) and also on parameter P0049;
■
The relays set for “Without Fault” are switched off.
In order to enable the CTW900 again and operate it normally, it is necessary to reset it, which can be done the
following ways:
■
Switching off the electronics power supply (XC5) and switching it back on (power-on reset);
■
Pressing the key or the “Reset” soft key (manual reset);
■
Automatically by means of the P0340 setting (auto-reset);
■
Via digital input set for the “Reset” function (P0263...P0270=20).
2.2 ALARMS
Alarms are warning messages that indicate a condition occurred and which may lead to a dangerous situation.
They do not stop the converter, but can lead to a fault condition if not removed.
The actuation of the alarms occurs as follows:
■
The alarm code is displayed on the keypad (HMI) and also on parameter P0048;
■
The “Status” LED becomes yellow;
■
The “Alarm” indication becomes active in the status word (P0680).
The alarms are automatically removed as soon as their causes disappear.
