Description
 Bag cutting machine step drive maintenance
Model: BD-36N
Fault phenomenon: there is a power light motor does not turn
Fault analysis: first open the shell without damage to the power supply circuit voltage components found in measurement, ask the customer to set parameters found a group of never mind, drive the IGBT single damage at the time of measurement. Measurement is not the same as a few groups of resistance value. After the replacement test external input pulse motor running normally.
Repair: the replacement of IGBT single fault relief.
Jiahong Serena stepper driver following fault repair:
One. The motor does not work
1 drive no power supply voltage
2 drive fuse
3 drive alarm (over voltage, under voltage, over current, over heat)
4 driver and motor connection
5 system parameter setting is improper
6 actuators enable signal to be blocked
7 port signal line contact is bad
8 driver circuit fault
9 machine card dead or malfunction
10 the impulse is too narrow, the frequency is too high, the pulse level is too low
Two. After the motor start blocking
1 command frequency is too high
2 load torque is too large
3 acceleration time is too short
4 load inertia is too large
5 power supply voltage reduction
Three. Motor running is not uniform, there is a jitter motor operation is not uniform
1 makes the pulse is not even 2 pulse is too narrow
3 pulse level is not correct
4 pulse level does not match the driver
5 signal noise
6 frequency and mechanical resonance
Four. Running irregular, forward and reverse swing
1 command pulse frequency and motor resonance
2 external interference
Five. Positioning is not allowed
1 plus deceleration time is too small
2 there is interference noise
3 system shielding bad
Six. Machine overheating:
1 working environment is too harsh, environmental temperature is too high
2 parameter selection is improper, such as the current is too large, more than the phase current
3 voltage is too high
Seven. Weakness or output reduction
1 power failure
2 internal error occurred in the winding
3 motor winding encounter case, the occurrence of inter phase short circuit or thread off
4 motor shaft off
5 the air gap between the stator and the rotor is too large.
6 power supply voltage is too low
Eight. Can not start
1 way of working
2 drive circuit fault
3 installation is not correct, or the motor itself bearing, stop and other faults so that the motor does not turn
