FEATURES :

• Built in auxiliary motor control
• Operation of up to three (3) line-started motors in addition to the motor controlled directly by the PowerFlex 400 drive
• When auxiliary motor control is enabled, the internal PID controller in the powerFlex 400 uses a reference and feedback signal to adjust the speed of the drive controlled motor such that the feedback signal follows the reference signal
• The speed of the drive controlled motor is reduced to account for the auxiliary motors additional output to the system
• A motor Interlock input identifies motors that are out of service and causes them to skipped over to the next available motor
• AutoSwap function also can be used which allows equal wear to be placed on each motor by periodically swapping the drive controlled and auxiliary motors
• Each motor in the system will over time be connected to the PowerFlex 400 drive and also directly to the AC line
• During an autoswap, the motor directly connected to the PowerFlex 400 drive is stopped and the contactor is opened
• The contactor of the next motor that will be controlled by the PowerFlex 400 drive is opened if running across the AC line
• Drive has an input which can be wired to a fire control panel or other fire/life safety systems allowing control of the drive to be overridden
• A purge input will start the drive at a programmable purge speed regardless of the selected start source, purge can occur and is operational at any time whether the drive is running or stopped
• A purge command will take precedence over a stop command from the comm port/network and over a SW enable command from the terminal block Not filtered emission class .
