10. Checking motor thermo sensor
The traveling motor has a thermo sensor embedded to monitor the motor temperature at all times.
If the temperature monitored by the sensor exceeds a certain level, the output current is restricted.
① Remove the motor thermo sensor connector.
② Set the tester to a resistance range of x 1000 Ω and measure the resistance between terminals using
the tester, according to the table given below.
③  Judgewhetherthesensorisgoodordefectiveusingthemeasuredvalues.
Norma value
10°C: approx. 20 kΩ, 20°C: approx. 13 kΩ
30°C: approx. 9 kΩ, 50°C: approx. 4.4 kΩ
