1. When the servo motor of the robot is running at a very low speed, it is fast and slow, just like a creeping machine. Low-speed prostrate servo motors are usually caused by low system gain. Please adjust the parameter N.10.N.11.N.12 to adjust the system gain appropriately, or the automatic gain adjustment function of the running driver.
2. The robot digital communication servo system MHMA2KW, once the testing machine is energized, the electric time oscillates and makes a loud noise, and then the driver will issue the No. 16 alarm. This phenomenon is usually caused by the driver gain being set too high, resulting in self-oscillation. Please adjust the parameters N.10, N.11, and N.12 and reduce the system gain appropriately.
Alarm No. 3.22 appears on the robot communication servo drive. The No. 22 alarm is an encoder failure alarm, and the general reasons are as follows: A. There is a problem with the encoder wiring: broken wire, short circuit. Please double-check for incorrect articulations; B. There is a problem with the encoder circuit board on the motor: misalignment, damage, etc. Please send it for repair.
4. In the form of azimuth control, the communication servo system of the robot outputs pulse and direction signals, but whether it is a forward rotation command or a reverse rotation command, the motor only rotates in one direction. In the form of azimuth control, the robot communication servo system can accept three control signals: pulse/direction, positive/negative pulse A/B orthogonal pulse. The driver is factory set to A/B quadrature pulse (No42 is 0), please change No42 to 3 (pulse/direction signal).
5. When using the robot communication servo system, can the servo servo system-ON be used as a signal to control the motor offline, so that the motor shaft can be rotated directly Although it is there? SRV-ON When the signal is disconnected, the motor can be taken offline (free condition), but do not use it to start or stop the motor. Frequent use of switching motors may damage the drive. If the offline function is required, it can be realized by switching the control form: assuming that the servo system requires azimuth control, the parameter No02 of the control form can be selected to be set to 4, that is, the second form is azimuth control, and the second is torque control. C-MODE switching control form: in the process of azimuth control, the signal C-MODE is turned over, so that the driver can operate in a certain way (i.e., azimuth control); When the demand is offline, the signaling C-MODE is enclosed so that the driver can operate in the second form (i.e. torque manipulation). Because the torque command is entered, the TRQR is not wired, so the motor output torque is zero, so it can be offline.
When the robot servo motor is repaired, when the industrial robot servo motor is incinerated, when the industrial robot servo motor is turned over to investigate the winding, it is necessary to turn over the industrial robot servo motor, the investigation is clearer, and the judgment is easier.
