Countermeasures |
|
---|---|---|---|
Power cannot be applied. |
Power switch is not turned ON. |
Power switch |
Turn the power switch ON. |
AC power cable is not plugged. |
Connection of the AC power cable. |
Surely plug it into the outlet. |
|
AC power cable is disconnected. |
Conduction of the AC power cable. |
Replace with the new AC power cable. |
|
Fuse is blown off. |
Fuse inside the holder. |
Contact your nearest distributor or send us an email. |
|
Minus torque is displayed. |
Error of the torque detector setting. |
Rotation direction of the motor attached to the torque detector. |
Switch the rotation direction of the motor. |
Attachment of the drive side or load side. |
Set up the torque detector again. |
||
Measures the overload. |
Try to measure after relieving the load. |
Replace with the suitable capacity torque detector. |
|
The value remains zero. | The torque signal is not applied. | The TQR light is not turned on. | The power of the torque detector is not turned on. Set the rotation direction switch to CW /CCW. |
Torque is not correct. |
Setting error |
Setting of the fixed value of torque detector, unit and torque zero correction value. |
Reset each item. |
Rotation speed is not correct. |
Setting error |
Setting of the rotation direction selecting switch and P/R selecting switch. |
Reset each item. |
Zero point is not correct. |
Torque zero correction value has not been set. |
Setting of the torque zero correction value. |
Set the torque zero correction value. |
Operate the overload measurement. |
Setting of torque zero correction value, torque acting on the measurement object, made or not made sudden start/stop. |
Contact your nearest distributor or send us an email. |
|
Shaft torque is applied while stopping. |
Remove the shaft connection to confirm the zero point. |
Change of the zero point is not necessary when it is positioned correctly. |
|
Analog voltage is not output. |
Minus voltage is output due to the setting error of torque detector. |
Whether the displayed torque is minus or minus voltage is output. |
Refer to the above “Minus torque is displayed”. |
The connection load is inappropriate. |
Connection load is 10 kΩ or more. |
Change the load connected. |
|
Analog voltage output is not correct. |
Temperature drift, etc. |
Whether the error is within measurement accuracy. |
Calibrate the voltage output. |
