Altivar 16 AC Drive Option card functions, logic input parameters Run/stop Available on: VW3A16201 + VW3A16104 . Logic input LI2. Function Run/stop with a single command. Applications Simplified sequences, remote control. f t 1 0 FW (RV) t 0 LI1 1 t Reset after fault Available on: VW3A16201 with or without VW3A16101 , VW3A16102 or VW3A16104 . 1 logic input LI1, LI2 or LI3. Function Erase fault and reset the drive (if the cause of the fault has been corrected). Applicable faults: overvoltage (OSF), motor overload (OLF), overbraking (ObF). Applications Remote reset. Simplified control sequence without line contactor. Motor power change Available on: VW3A16201 + VW3A16104 .
1 logic input LI1, LI2 or LI3. Function Use of one drive on either of two motors with different ratings. Switching between motors is performed by an appropriate drive output sequence. The switching must be made with the drive disabled. This function allows optimization of both motors. The following parameters are automatically changed by the logic command: - Volts/frequency ratio (UFr) - Slip compensation - ItH (thermal protection inhibited) - Current threshold of brake control logic - Automatic DC injection Adjustments with option VW3A16104 are possible for a power ratio of 1 to 5. Applications Material handling with several movements, 2 of which are not simultaneous.
Machines with several sections, 2 of which do not operate simultaneously. 25
