Altivar
variable speed drives
Limiting low speed operating time
The motor is stopped automatically after a period of operation at low speed (LSP).
This time can be set between 0.1 and 999 seconds (0 corresponds to an unlimited
time).
The motor restarts automatically on a ramp when the reference reappears.
This function is suitable for automatic stops/starts, especially in pump applications.
Configuration of analog input AI1
This is used to modify the specifications, for either voltage or current, of analog input
AI1.
Factory-set configuration: 0-5 V (internal power supply).
Other possible values via external power supply: 0-10 V, X-Y mA by programming X
and Y with 0 to 20 mA.
Automatic restart
This function enables the drive to be restarted automatically after it has locked in
fault mode, provided the relevant fault has disappeared and the other operating
conditions permit a restart.
This restart is performed by a series of automatic attempts separated by increasingly
long waiting periods of 1 s, 5 s, 10 s, then 1 min for subsequent periods.
If the drive has not restarted after 6 minutes, it locks and the procedure is abandoned
until the drive is powered down and back up again.
Factory-set configuration: Function inactive.
Restarting is permitted with the following faults:
v Drive thermal overload
v Motor thermal overload
v Line overvoltage
v Overvoltage during deceleration
v Motor overload
v Motor underload
v Output phase loss
v Input phase loss (1)
v Line undervoltage (2)
v Modbus serial link
For this type of fault, the fault relay remains activated if the function has been
configured.
This function requires the speed reference and the direction of operation to be
maintained, and is only compatible with 2-wire level control.
This function is suitable for machines or installations which are in continuous
operation or are not monitored, and where a restart will not endanger equipment or
personnel in any way.
Automatic catching of a spinning load with speed detection (“catch on the fly”)
Used to restart the motor smoothly after one of the following events:
v Loss of line supply or power off
v Fault reset or automatic restart
v Freewheel stop
Once the event is over, the actual motor speed is detected in order to restart on a
ramp at this speed and return to the reference speed. The speed detection time can
be up to 1 s (typical value) depending on the initial deviation.
Factory-set configuration: Function inactive.
This function requires the “automatic DC injection braking” function to be disabled.
This function is suitable for machines for which the loss of motor speed is negligible
during the power failure (machines with high inertia).
(1) The “input phase loss” fault is only accessible on drives with a three-phase power supply,
if monitoring of the fault has been enabled (factory-set configuration: enabled).
(2) The drive will restart as soon as the “undervoltage” fault disappears, regardless of whether
the function is active.
