Do not connect this terminal to the ground. --- FS Frequency reference power supply output +10 V DC power supply for the FV terminal. Allowable load current: 20 mA max.
Frequency setting input FV Frequency reference input (Voltage directive) With a 0 V to 10 V DC voltage input, the maximum frequency is set at 10 V. To set the maximum frequency at 10 V or lower, set A014. Input impedance 10 kΩ Allowable input voltage range: −0.3 to +12 V DC FV2 Auxiliary frequency reference input (Voltage directive) With a 0 to 10 V DC voltage input, the FV2 signal is added to the frequency reference signal of the FV or FI terminal. If the setting is changed, the frequency reference can be input even with the FV2 terminal independently.
Input impedance 10 kΩ Allowable input voltage 0 to ±12 V DC FI Frequency reference input (Current directive) With a 4 to 20 mA DC current input, the maximum frequency is set at 20 mA. The FI signal is only active when the AT terminal is ON. Allocate the AT function to the multi-function input terminal. Input impedance 100 Ω Allowable max. current: 24 mA Monitor output AM Analog monitor (Voltage) This terminal outputs a signal selected from the "0 V to 10 V DC Voltage Output" monitor items:
Output frequency, Output current, Output torque (with/without sign), Output voltage, Input voltage, Electronic thermal relay load rate, LAD frequency, Motor temperature, Cooling fin temperature, and General-purpose output. Allowable max. current: 2 mA AMI Analog monitor (Current) This terminal outputs a signal selected from the "4 to 20 mA DC Current Output" monitor items: Output frequency, Output current, Output torque (with/without sign), Output voltage, Input voltage, Electronic thermal relay load rate, LAD frequency, Motor temperature, Cooling fin temperature, and General-purpose output. Allowable load impedance: 250 Ω max.
Digital (con- tact) Monitor output FM Multi-function digital output This terminal outputs a signal selected from the "0 to 10 V DC Voltage Output (PWM)" monitor items: Output frequency, Output current, Output torque (with/without sign), Output voltage, Input voltage, Electronic thermal relay load rate, LAD frequency, Motor temperature, Cooling fin temperature, General-purpose output, Digital output frequency, and Digital current monitor. "Digital output frequency", and "Digital current monitor" output a digital pulse at 0/10 V DC pulse voltage and 50% duty ratio. Allowable max. current: 1.2 mA Max. frequency:
3.6 kHz Power supply P24 Interface power supply terminal 24 V DC power supply for contact input signal. When the source logic is selected, this terminal functions as the contact input common terminal. Allowable max. output current: 100 mA SC Input common Common terminal for the interface power supply (P24) terminal, thermistor input (TH) terminal and digital monitor (FM) terminal. When the sink logic is selected, this terminal functions as the contact input common terminal. Do not connect this terminal to the ground. --- Contact input RUN com- mand FW Forward rotation command terminal When the FW signal is ON, the motor runs forward. When it is OFF, the motor decelerates and stops.
[Contact input ON condition] Voltage between each input terminal and the SN terminal: 18 V DC or more. Input impedance between each input terminal and the SN terminal: 4.7 kΩ Allowable max. voltage: Voltage between each input terminal and the SN terminal: 27 V DC Load current at 27 V DC power supply voltage: Approx. 5.6 mA Func- tion/ Selec- tion S1 Multi-function input Select 8 functions from among the 69 functions and allocate them to from terminals S1 to S8. Note: Only terminals S1 and S3 can be used for the emergency shutoff function. For details, refer to Emergency Shutoff Function on page 45.
S2 S3 S4 S5 S6 S7 S8 SN Multi-function input common The sink and source logic for contact input can be switched by connecting a short-circuit bar on the control terminal block. Short-circuiting P24 and SC → Sink logic, Short-circuiting SC and SN → Source logic To drive contact input via an external power supply, remove the short- circuit bar and connect terminal SN to the external interface circuit. ---
