Causes | Check point | 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. | LED displays are all lit out. | 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. |
