Response to external fault (P3.9.2)
An alarm message or a fault action and message is generated by an external fault signal in one of the
programmable digital inputs (DI3 by default) using parameters Ex Fault Close (P3.5.1.7) and Ex Fault Open
(P3.5.1.8). The information can also be programmed into any of the relay outputs.
Motor thermal protection (P3.9.6 through P3.9.10)
The motor thermal protection protects the motor from overheating. The drive is capable of supplying higher than
nominal current to the motor. If the load requires this high current, there is a risk that the motor will thermally

Default ID
749 Defines the response to a PID1 fault.
Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
757 Defines the response to a PID2 fault.
Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
Not Used 739 Defines the source signal to monitor for
TempAlarm Limit (P3.9.26) and TempFault
Limit (P3.9.27) triggering.
Settings:
0 = Not used
1 = Temperature Input 1
2 = Temperature Input 2
3 = Temperature Input 3
4 = Temperature Inputs 1 & 2
5 = Temperature Inputs 2 & 3
6 = Temperature Inputs 1 & 3
130 741 Defines the temperature that TempFault
Signal (P3.9.25) must reach for triggering
an alarm.
155 742 Defines the temperature that TempFault
Signal (P3.9.25) must reach for triggering a
fault.
740 Defines the response action when
TempFault Signal (P3.9.25) has past
TempFault Limit (P3.9.27). Response
settings are as follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
14061 Defines the response action to a Run
Interlock Fault. This requires Mot. Interlock
Start (P3.2.11) to be enabled, Run
Interlock 1 (P3.5.1.12) or Run Interlock 2
(P3.5.1.13) to be defined to a digital input
and a value defined for Run Interlock Proof
(P3.2.13) other than 0.
