E101—excessive current through hardware
Troubleshooting steps
check the motor is good or bad: using multimeter(Ω side) to measure whether the motor outlet foot 4# short to 1#、2#、3#; whether the impedance of motor is same between U【3】、V【2】、W【1】
check if the angle of motor is right: press
and ± go into U6 interface, then press
and see if the motor angle in the range of 252 ±5, if the deviation of motor angle is too big, then motor acceleration or scram will cause large current or speed uncontrolled phenomena
check the impedance of foot 1# to 3# of Q3 ∽ Q8: 10K or so
check the impedance of foot 2~7# to 12#(safety line) in the MPU U8, should be around 0.7M and voltage 3.8V when standby.
check the impedance of foot 14#、15#、16# to 12#(safety line) in the MPU U8, should be around 10k and voltage 0V when standby.
Check the value of resistance of R169 in MPU: 1K; C101 ends of impedance: 6.5k; voltage 3.2V when standby.
check the impedance of foot 1# to 12#(safety line) in the MPU U8: 1.6m or so; voltage 15V or so when standby.
check the impedance of foot 1#、7# to 4#(safety line) in the MPU U20: 13.5k; voltage 1.46V when standby.
Check if the grating loose, or have friction with sensors in encoder board.
