Latch
ON
The alarm is stored. The programmed actions (e.g. opening
the OK relay) are enabled. This status is kept latched even if
the fault condition is restored. A Reset command is required
before a restart.
OFF
In case of alarm, the drive is disabled and the programmed
functions are enabled. The alarm is not latched. When the
failure is removed, the alarm is automatically reset and the
device tries restarting.
Ok relay open
ON
An alarm causes the opening of the potential isolated contact
between terminals 35 and 36.
OFF
The alarm does not cause the opening of the potential free
contact of the OK relay.
Hold off time
Delay time between the alarm condition detection and the alarm activation. If an alarm
condition occurs the alarm stay OFF for the
Hold off time
. When this time is elapsed
and the alarm is still present, the alarm activates.
Restart time
If
Latch
=Off and the alarm condition persists even after the time defined via
Restart
time
, the alarm is stored and no restart is possible (
Latch
=OFF).

In Terminal mode to reset the fault the terminals enable and start must be at zero voltage. The
occurrence of a failure is indicated in the display of the keypad. If “Latch”=ON is selected,
a Reset command is necessary. This can be carried out, for example, by pressing the CANC
key on the keypad. If a second error occurs before the first one was reset, the text “Multiple
failures” will appear in the display. In this case, a reset is only possible via
Failure reset
parameter in the SPEC FUNCTIONS menu. The reset can be obtained by pressing the E
key with a disabled inverter.
Failure supply
Failure on the supply voltage.
It indicates a failure on the internal voltage of the regulation circuit. The message “Failure
supply” occurs if an enabled converter has no voltage on the U2 and V2 terminals. If
it is of a short duration and restored, a possible digital output prepared for the message
is set to a Low condition. A normal reset can be carried out.
Undervoltage
AC Input undervoltage.
In case of an AC Input voltage when the regulation is enabled (
Enable drive =
Enabled)
the message
Undervoltage
appears. The converter is immediately disabled. To this
purpose an intervention threshold is preset via the
Undervolt thr
parameter.
If the alarm is not saved (Latch=OFF), the drive tries to start automatically after the
voltage has been restored. Using the ramp, when the voltage is restored, if the function
Auto capture is active, the ramp output is set to the value corresponding to the current
motor speed. This avoids speed jumps.
Overvoltage
Armature overvoltage. Ther message appears when the armature voltage exceeds the
value set via
Max out voltage
by 20%.
If the alarm is not saved (Latch = OFF), the drive will attempt to restart automatically
after the voltage has been restored.
Using the ramp, when the voltage is restored, if the function Auto capture is active, the
ramp output is set to the value corresponding to the current motor speed. This avoids
speed jumps.
Overspeed
This alarm condition is signalled if the speed limit set in the
Overspeed thr
parameter
is exceeded.
