Reset - Autoreset - Protections and alarms

F
UNCTION
Operation to be executed when the inverter is in alarm state. Three possibilities are available:
a) Keyboard reset:
simultaneously press the ⇑ ⇑ ⇑ ⇑ ⇑ and ⇓ ⇓ ⇓ ⇓ ⇓ keys; the action will have effect when the keys are released.
b) Terminal board reset:
Reset
it can only be performed if one of the programmable control inputs has been configured as Ix-
RES. In this case, the reset operation is enabled when switching from active to inactive control.
c) Cut the inverter supply off
wait until it is completely off, supply the inverter again.
As an alternative to manual reset, this function allows an automatic restart in case of lock due to protection tripping. It can
Autore-
only be enabled if the lock is due to: overcurrent, overvoltage, undervoltage, momentary overload, external alarm (b-11)

and is controlled by the parameters defined on the following table:

In case of lock, it automatically restarts the inverter.

[ 0 ]
0 = off 1 = on
During autoreset, it disables the lock signalling contacts on the terminal board
[ 1 ]
if allowed, through parameter setting, to perform the alarm function.
0.1 - 60.0
Defines the time, as regards the lock enabling moment, after which the autoreset
[ 5 ]
(restart) is executed.
1 - 250
Sets the max. number of restart attempts after which the inverter remains in lock
[ 1 ] state. To restart, execute a manual reset.
Configuration memory error. It is enabled at inverter startup if the configuration memory is not
working properly. To avoid this, try to turn the inverter off and restart it after some minutes.
Parameter memory error. It is enabled if the memory contains inconsistent parameters. Causes:
accidental loss of parameters (turning off during storage phase), memory failure. In case of
accidental loss: turn the inverter off and restart it after some minutes. The factory-preset parameters
will be stored.
External protection: enabled by the EXTFLT input on terminal board. Autoreset can be enabled only
if parameter b-11=1.
Overcurrent protection: enabled when the output current exceeds, even momentary, the max.
allowed threshold to protect the inverter. It signals shortcircuits between phases and to ground too.
Overvoltage protection: enabled when the voltage at the filter capacitor ends exceeds the max.
programmed threshold to protect the inverter.
Undervoltage protection: enabled when the voltage at the filter capacitor ends falls below the min.
threshold programmed to avoid troubles due to torque reduction. Autoreset is allowed. If b-37=0,
the alarm storage is disabled.
Overtemperature protection: enabled when the heat sink temperature exceeds the max. threshold
programmed to protect the inverter. Autoreset is not allowed.
Inverter overload protection: enabled when the direct current exceeds the max. threshold for the
max. allowed time (IxT) to protect the inverter. Autoreset is not allowed.
Motor overload protection: enabled when the direct current exceeds the max. threshold for the max.

allowed time (I xT), to protect the motor. The levels and times depend on setting of the motor
characteristic data. Autoreset is not allowed.
Braking resistor overload protection: enabled when the power dissipated by the braking resistor
exceeds the max. threshold for the max. allowed time. The levels and times depend on setting of
the resistor characteristic. Autoreset is not allowed.
Protection for momentary motor overload: it is active, after enabling (b-17=1), when the torque
delivered by the motor exceeds the programmed level for the preset time, to protect the connected
mechanical parts or the worked material.
Fuse breakage protection: enabled in case of inner fuse breakage. Autoreset is not allowed.
