Digital Input Function Selections (H1-01 to H1-05) 3 Multi-step speed reference 1 4 Multi-step speed reference 2 5 Mulit-step speed reference 3 6 Jog frequency command (higher priority than multi- step speed reference) 7 Accel/decel time selection 1 F Not used (Set when a terminal is not used) 14 Fault reset (Reset when turned ON) 19 PI control disable 20 to 2F External fault; Input mode: NO contact/NC contact, Detection mode: Normal/during operation 71 Speed/torque control change (ON: Torque control) 77 Speed control (ASR) gain switching (ON: C5-03) Digital Output Function Selections (H2-01 and H2-02 0 During run 1 (ON:
run command is ON or voltage is being output) 6 Inverter operation ready; READY: After initialization or no faults F Not used. (Set when the terminal is not used.) 10 Minor fault (Alarm) (ON: Alarm displayed) 1A During reverse run (ON: During reverse run) 1F Motor overload (OL1, including OH3) pre-alarm (ON: 90% or more of the detection level) 30 During torque limit (current limit) (ON: During torque limit) 32 Activated if the ASR is operating for torque limit. The ASR output becomes the torque reference, the motor is rotating at the speed limit.
