The bus voltage of the control loop or main loop is too low or the speed feedback is abnormal.
3. Guide customers to on-site solutions
1, the control loop bus voltage is too low: Use a multimeter to confirm the control loop (L1C, L2C) power supply voltage value is too low. The inter-phase voltage of 220V class drivers is lower than 198V and 380V class drivers are lower than 342V, which will cause the bus voltage to be too low. Read the control loop bus voltage monitoring value (H0B57), 220V class driver below 235V, 380V class driver phase below 451V.
2. Whether the input voltage meets the requirements. Using a multimeter, check the voltage value of the main loop (R, S, T) or the three-phase input voltage is out of phase.
3. Whether the bus voltage meets the requirements. H0B-26 can be used to check whether the bus voltage of the driver main loop is consistent with the measured bus voltage. Check whether the busbar voltage is too high or too low. The PN voltage meets the requirements. * (15%) * 2 * (10%) * 2 IN min PN IN max V V V.
4, just power-on detection speed feedback exceeds 10rpm, confirm whether there is reverse drag or encoder feedback abnormal H0B07.
5. The cable connection is abnormal. When wiring IS620P-SizeE frame machines, it is necessary to connect the negative bus short connector of the power terminal; otherwise, the NRD will be alerted, as shown in the blue mark in the following figure.
In the selection and debugging of servo system, the inertia problem is often encountered. Its specific performance is as follows:
In the selection of servo system, in addition to considering the torque and rated speed of the motor and other factors, we also need to calculate the inertia of the mechanical system to the motor shaft, and then select the motor with the appropriate inertia size according to the actual action requirements of the machine and the quality requirements of the workpiece; In debugging, the correct setting of inertia ratio parameters is the premise of giving full play to the best performance of the mechanical and servo system. This point is particularly prominent in systems requiring high speed and precision, so there is a problem of inertia matching.
