variable speed drives
Fault relay, unlocking
The fault relay is energized when the drive is powered up and is not faulty.
It opens in the event of a fault or when the drive is powered down.
The drive can be unlocked after a fault in one of the following ways:
v By powering down the drive until the display disappears completely, then
powering back up
v By activating the logic input associated with the “fault reset” function, if the function
is enabled
v By enabling the “automatic restart” function
Drive thermal protection
Thermal protection is integrated in the drive. When the fault is detected, it locks the
drive.
Depending on the model, the drive is equipped with a fan.
The drive optimizes management of fan operation in order to reduce the amount of
maintenance work and the equipment noise level.
Motor thermal protection
The theoretical temperature rise of the motor is continuously calculated to provide
thermal protection.
The drive calculates this temperature rise using the following elements:
v The operating frequency
v The current taken by the motor
v The operating time
v The type of motor ventilation (self-cooled or force-cooled)
Thermal protection can be set at anything from 0.2 times the nominal drive current.
It must be set to the nominal current indicated on the motor rating plate.
Note: When the power supply is de-energized, the motor thermal state may or may not be
stored, depending on the chosen configuration.
Monitoring
The display shows the state of the drive or, if selected, one of the following values:
v Frequency reference
v Output frequency applied to the motor
v Motor current
v Line voltage
v Output power
v Motor thermal state
v Drive thermal state
v PID error
v PID feedback
v PID reference
v Motor operating status (stop, forward, reverse, run, acceleration, deceleration,
braking, freewheel stop, etc.)
