Input signals

Turn on the STF signal to start forward rotation and turn it off t o stop. Turn on the STF signal to start reverse rotation and turn it off t o stop. You can select mult iple speeds by shorting any of terminals RH, RM and RL signal. The priorities of the speed commands are in order of jog, multi-speed sett ing (RH, RM, RL, REX) and AU. Common terminal for contact inputs (terminal s STF, STR, RH, RM, RL) and indicator connection (terminal FM). Isolated from terminals 5 and SE. When connecting t he transistor output (open collector output) of a programma ble controller (PLC) etc., connect the positive external power supply for transistor output to this terminal to prevent a malfunction due to l eakage current. It can be used as a 24V 0.1A DC power supply across PC-SD termi nals. Acts as the common termi nal of the contact input signals when source l ogic is selected. 5VDC, permissible l oad current 10mA.

Inputting 0 to 5VDC (0 to 10V) provides the maximum output frequency at 5V (10V) and makes input and output proportional. Use Pr. 73 "0 to 5V, 0 to 10V selection" to switch between 5V and 10V. Input resistance 10kΩ. Maximum permissible input voltage 20V.

Input 4 to 20mA DC. Factory-adjusted to be 0Hz at 4mA and 60Hz <50Hz for EC version> at 20mA. Maximum permissible input current 30mA. Input resistance approximately. 250Ω. Turn ON signal AU for current input. Use any of Pr. 60 to Pr. 63 (input terminal function selection) t o set the AU signal.

A stop command is given if STF and STR signal turn ON at the same time.

The terminal function changes with the setting of input terminal function selection (Pr. 60 to Pr. 63). (*4)
