Connecting voltmeter to terminal AM

You can connect them in parallel. Connect the voltmeters in parallel, paying attention to the following: - The output current should not exceed the permissib... More Details >>

"Err" is displayed when STF signal turns ON

Possible causes are:1. The reset signal (RES) is ON. 2. The built-in CPU is not working properly due to contact faults of the inverter parts. Check the exte... More Details >>

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>

Inverter input power supply

Square wave input is not recommended since it can cause failures (for example, damage the diode bridge). More Details >>

FR-A800-R2R

It depends on machine specifications. It depends on the accuracy of the line speed input and parameter setting of material thickness. More Details >>

PTC thermistor function

The function is only for overheat protection. It does not affect the torque accuracy. More Details >>

Writing set frequency by CC-Link communication

No error will occur because up to 400 Hz that is the upper limit of the setting range can be written. More Details >>

Current value monitor

The current value can be displayed on the operation panel without regard to the setting of monitor-related parameters. As the current value remains 0 A, the ... More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Inverter current value

1. As the measurement condition is unknown, the possible cases are as follows: - If you measured the current on the input side of the inverter, since the cu... More Details >>
