In momentary power loss operation continuation mode, speed search operation is performedbeginning with current output frequency, regardless of the existence of search command. Aftercompletion of speed search, the operation is performed according to the run command.2. Determine a sequence so that FWD/REV run command enters at the same time or later thansearch command.Example of SequenceRELAY 1RELAY 1 RELAY 2SEACHCOMMANDFWD / REV RUNCOMMAND3. More than two search commands of set values 61 and 62 cannot be set.15 Integral value reset (set value = 65)Value I is reset to 0 when an integral value reset command is input from multifunctioncontact inputs (terminal 5 ~ 8, set 65 either to Sn-15 to 18)16 PID control cancel (set value = 66)PID control circuit can be canceled by multifunction contact input signal. Set 66either to Sn-15 to 18 and close the contact (either terminal 5 to 8) during running.Then the PID control circuit is canceled and the aimed value signal is used as afrequency reference signal without being changed. In this case, the signal input levelis 0 the 10V (or 4 to 20mA)/0 to 100%.94
