5.1. What Happens when a Protective Device Trips
operating the drive in emergency conditions, carefully read this section and the
What To Do When an Alarm Trips
The drive alarms are detailed below.
When a protection / alarm trips:
1) the ALARM LED on the keypad comes on;
2) the page displayed on the keypad is the root page of the FAULT LIST;
3) the FAULT LIST is refreshed;
In factory-setting, when the drive is switched on after an alarm has tripped—which has not been reset—it is kept in
emergency condition.
If the drive is in emergency mode when switched on, this could be due to an alarm tripped before the drive was reset.
To avoid storing the alarms tripped before the drive is switched off, set parameter C257 in the Autoreset Menu.
The drive stores the moment when an alarm trips to the FAULT LIST (supply time and operation time). The drive status
when the alarm tripped and some measures sampled when the alarm tripped are also stored to the Fault List.
The readout and storage of the fault list can be very useful to detect the cause responsible for the alarm and its possible
solution (see also the Fault List Menu/Power Off List Menu in the Sinus Penta’s Programming Instructions manual).
Alarms A001 to A039 relate to the main microcontroller (DSP Motorola) of the control
board, which detected a fault on the control board itself. No fault list is available for

Before resetting any alarm, deactivate the
drive and prevent the connected motor from running at uncontrolled speed.
