Power supply phase sequence

No problem.The inverter converts AC power into DC power and then into AC (PWM) power output again. Therefore, it is not influenced by the power supply phase ... More Details >>

Applicable motors

In addition to the dedicated motor (SF-VR series), the SF-JR series motor with an encoder can be used. You can also use a standard motor by combining it with... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>

Installing contactor on input side

It is not recommended to install a contactor on the input side and connect the auxiliary contact to the terminal STF of the inverter for the following reason... More Details >>

Speed does not exceed 46 Hz

Since the inverter displayed "0.00" instead of an error when the inverter speed dropped to 0 Hz and stopped by holding the winding machine by hand, it is con... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

Long wire to terminal FM

Although you can connect an analog or digital indicator to the terminal FM, use an analog indicator since the wiring length is long. (The maximum wiring leng... More Details >>

Earthing (grounding) of FR-A7NC (E kit)

There is no problem, however, earthing (grounding) from each FG terminal is recommended to avoid the influence of noises. More Details >>

PID control of CC-Link communication

When performing the PID control by CC-Link communication, the X14 signal is disabled. More Details >>

Instruction code execution request of CC-Link communication

Only one instruction is executed. The instruction to be executed is not fixed. More Details >>
