[Overspeed Val]
Speed value (rpm) at which an “Overspeed” fault (F25) will occur.
Notes: Typically set at 110% of Par 162 [Max Feedback Spd]. See Chapter 4 for a list
of fault and alarm descriptions. This parameter was added for firmware version
3.001.

1380 [Drive Alarm 1]
Alarm conditions that currently exist in the drive. For each bit, 1 = Condition true, and 0 = Condition false.
Bit 0
“DigInCflctA” - Digital input functions are in conflict.
Bit 1
“DigInCflctB” - A digital Start input has been configured without a Stop input or other functions are in conflict.
Bit 2
“DigInCflctC” - More than one physical input has been configured for the same input function.
Bit 3
“BipolarCflct” - Parameter 1322 [Direction Mode] is set to “Bipolar” or “Reverse Dis” and one or more of the following digital input
functions is configured: “Fwd/Reverse,” “Run Forward,” “Run Reverse,” “Jog Forward” or “Jog Reverse.”
Bit 4
“Ref Cflct” - Multiple speed or position references are configured.
Bit 5
“CntactrCflct” - Contactor input functions are in conflict.
Bit 6
“FB Cfg Cflct” - A speed feedback configuration error has occurred or is being provided by multiple sources.
Bit 7
“Overvoltage” - There is an overvoltage on the armature circuit.
Bit 8
“Over Temp” - The motor has exceeded its temperature rating [as signaled by the thermistor (PTC) or thermal switch connected to the drive
terminals 78 and 79].
Bit 9
“Aux Input” - An auxiliary input interlock is open or a voltage (15…30 V) or reference signal is missing for the digital input set to 14 “Aux
Fault” (only updates if Par 354 [Aux Inp Flt Cfg] is set to 1 “Alarm”).
Bit 10 “Field Loss” - The field current is too low.
Bit 11 “SpdFdbk Loss” - The drive is not receiving a speed feedback signal.
Bit 12 “PwrUp Start” - Indicates that the drive is starting or has automatically resumed running at commanded speed after drive input power was
restored.
Bit 13 “Mtr Overload” - Indicates when the Motor Overload alarm level has been reached.
Bit 14 “FldCfg Cflct” - Indicates a field configuration conflict.
Bit 15 “Spd Fdbk Err” - Indicates an encoder or resolver error.
Notes: See Chapter 4 -Troubleshooting on page
for information. The name of bit 11 was changed from “Encoder Loss” and bits 13 and 14 were
added for firmware version 3.001. The name of bit 4 “AnalogCflct”, bit 6 “Encoder Cflct”, and bit 11 “Feedback Loss” were changed and bit 15 was
added for firmware version 5.002.
