Altivar
variable speed drives
Underload detection
This function stops the motor when it is underloaded. The function is active in
steady state.
If the current is below an underload threshold for an adjustable period of time,
the drive locks in underload fault mode.
The current threshold is adjustable between 20% and 100% of the nominal motor
current value.
Hysteresis of 10% is applied to this threshold to confirm the end of underload
conditions. The time delay is adjustable up to 100 s. When this parameter is at 0,
the function is deactivated.
This function is particularly suitable for protecting pumps during cavitation.
Overload detection
This function stops the motor when it is overloaded. The function is active in steady
state.
If the motor current is higher than an overload threshold for an adjustable period of
time, the drive locks in overload fault mode.
The overload threshold can be set to between 70% and 150% of the nominal motor
current.
Hysteresis of 10% is applied to this threshold to confirm the end of overload
conditions.
The time delay can be set at anything up to 100 s. When this parameter is at 0,
the function is deactivated.
Fault acknowledgment
This is used to clear the stored fault and restart the drive if the cause of the fault has
disappeared.
The fault is cleared by a transition of the logic input LI which is assigned to this
function.
Factory-set configuration: Function inactive.
The restart conditions after a reset are the same as those of a normal power-up.
The following faults can be reset (1): drive thermal overload, motor thermal overload,
line overvoltage, overvoltage on deceleration, overspeed, input phase loss (2), etc.
Parameter protection by confidential code
This function protects the drive configuration using an access code.
Configuration of logic output LO+
Logic output LO+ enables remote signalling of the following information as required:
v Malfunction
v Operation
v Frequency threshold attained
v High speed attained
v Current threshold attained
v Frequency reference attained
v Motor thermal state attained
v 4-20 mA monitoring
v Underload detected
v Overload detected
v Operation of the auxiliary pump with the “Control in single variable mode with
auxiliary pump” function
Configuration of analog output AO1
Analog output AO1 enables remote signalling of the following information as
required:
v Motor current
v Motor frequency
v Ramp output
v PID error
v PID feedback
v PID reference
v Output power
v Motor thermal state
v Drive thermal state
(1) See the complete list of faults in the Altivar
website at “www.schneider-electric.us”.
(2) 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).
