FR-A800 "Parameter for the communication setting"

These parameters are used for the communication compatible with the communication protocol of the Ethernet IP of the HMS optional circuit board (A8NEIP_2P). More Details >>

Calculation of inverter acceleration and deceleration time

Refer to the Technical Sheet No.23 (Capacity Selection and Continuous Operation) for reference for selection. Optional capacity selection software is also pr... More Details >>

Control wire of FR-HC RDY signal

The contact between the terminals RDY and SE is open collector output.Operation is:Normal: Non-conductiveFault: Conductive More Details >>

Frequency adjustment using potentiometer

Since the inverter is initially set to 0 Hz for 0 V and 60 Hz for 5 V, you can calculate the frequency for a certain voltage value. The equation is "Output f... More Details >>

Rotation ripple at low speed

The rotation ripple data for 1.5 kW is shown below.Drive unit: MD-CX520-1.5KMotor: MM-CF152Load: None (motor alone), carrier frequency: 2 kHz, wiring length:... More Details >>

CC-Link

No problem. The inverter actually occupies the reserved bits and does not use them. More Details >>

External installationRated current

Since the external thermal prevents the motor from being overheated, install it between the output terminal of the inverter and the motor.The rated current i... More Details >>

Frequency setting

It is not stored in a parameter but memorized as the frequency setting value after acceleration by the acceleration signal.You can also choose whether or not... More Details >>

Operation panel (FR-PA02)

Set Pr.146 (Built-in potentiometer switching) to "0".This allows for using the potentiometer built in the FR-PA02 to set the frequency.(Set this parameter to... More Details >>

10 VDC voltage from terminal 10

Setting Pr.73 to "0" does not generate 10 VDC output.The inverter itself only has 5 V at the terminal 10.Setting this parameter to "0" allows 10 V input betw... More Details >>
