PA7300 Instruction Manual - TECO-Westinghouse Motor Company

7 External baseblock (set value = 09)Baseblock is performed when "open". All other operations are the same as when aset value = 8.8 Accel/decel speed prohibit command (set value = 0A)As long as accel/decel speed prohibit command is input, accel/decel speed isprohibited and the output frequency at that time is held. When stop command is input,accel/decel speed prohibit state is freed and the system enters stop state. The figurebelow shows a time chart.FWD RUNACCEL/DECELSPEEDPROHIBITCOMMANDFREQUENCYREF.OUTPUT FREQUENCYNote: If the run command is input again after the stop command is input while the accel/decel prohibitcommand is input, the holding output frequency is stored unless the accel/decel prohibit commandis released. Therefore, operation is performed at the stored output frequency. Also when the powersupply is turned OFF in the accel/decel prohibit command input status, the holding output frequencyis still stored.9 Inverter overheat alarm (set value = 0B)As long as an inverter overheat signal is input, “Over Heat OH2” blinks a the digitaloperator.10 UP command/DOWN command (set value = 10, 11)Acceleration/deceleration is performed by inputting the UP/DOWN commandswithout changing frequency reference in the forward (reverse) run command inputstatus, and operation can be performed at a desired speed.Set value = 10: UP commandSet value = 11: DOWN commandUP command Closed Open Open ClosedDOWN command Open Closed Open ClosedStatusAccel(UP)Decel(DOWN)HoldHold89
