(3) Input / Output Signal
① Input Signal
There are 7 different input signals : " Rotate Command (START) ", " Rotating Direction Setting (DIR_IN) ",
" Rotates Motor at " Centering " speed (500min
(POINT 0) ", " Speed Point Select 1 (POINT 1) " and " Motor Select (MT_SEL) ". These signals are DC+24V
signals from an external signal source. Please use a separate power source that is capable of supplying
DC+24V ± 10%, 100mA. Refer to Fig. 22 for connections.
② Output Signal Ⅰ
There are 6 separate output signals : " Rotating (RUN) ", " Rotating Direction (DIR_OUT) ", " Error (ERR) ",
" WARNING (WARNING) ", " Speed Achievement (COIN) " and " Motor Select (SEL_MT) ". These signals are
MOSS Relay Contact Connections. The output current can be connected to either sinking or sourcing.
Voltage and Current Specifications
・Applied Voltage (V) ≦ DC+30V
・Working Current (lp) ≦ 100mA
Use an external power source for output circuits. It is recommended to use the same DC+24V power source
used for input signals. Please refer to Fig. 23 for connections.
