TM 5-3895-374-24-1 Configuration, special functions, settings Parameters Selection Factory setting Description + speed /-speed No / Yes No During + speed / - speed operation, the logic LI1 "+ speed", frequency increases in absolute value in line with the acceleration ramp, the maximum frequency is determined by the speed reference L12 "- speed ", frequency decreases in absolute value in line with the deceleration ramp Validation of the controller and selection of rotational direction are controlled by inputs FW (forward) and RV (reverse) Low speed LSP can be adjusted, and is validated by FW or RV The + speed / - speed mode cannot be used when preset speeds are selected (2, 4 or 8 levels) Reduce voltage No / Yes No Enables reduced voltage to be applied to the in FW direction Logic input motor Remote Yes motor voltage reduced in permanent operating mode During acceleration and deceleration, voltage is normal Logic Input motor voltage is reduced for FW operation when one of the logic inputs assigned to this function is validated The rate of voltage reduction applied to the motor in permanent operating mode is adjustable ·• 100 % full voltage applied, ·• 10 % 10 % of the voltage applied Applications reduction of motor current on machines with low loads and high inertia, improved stability Remote the voltage reduction applied to the motor is systematically reduced for FW and RV operation to a value determined by the reference input reassigned to this function The speed reference is then provided by the preset speeds, or HSP, or "+ speed / - speed" This function should not be used together with RV voltage reduction nor with remote current limitation reduction Applications squirrel cage motors (page 3-233)
