4.3. Light-load detection mode
When F342 (Light-load detection mode) is used, the sign of the positive and negative can be judged for F335~F340.
F342 is set as follows.
1) Set “+128" for the detection with the sign.
2) Set “+0" when it is rolling up of the forward rotation. When it is small compared with the detection
level, it is judged a light load.
Set “+64" when it is rolling up of the reverse rotation. When it is large compared with the detection
level, it is judged a light load.
3) Judge the positive and negative of each mode according to the table below, and total the value.
4) Set the total of 1)~3) to F342.
Ex.) Forward: roll up, reverse: roll down, d
etection with torque
1)The torque of the table below is detected by the light load.
2)Setup value of F335~F340 and F342 becomes a table below.
3)Set the following parameters.
