8.9.2 Monitoring of the speed deviation
This function extension is available from version 01.09!
Monitoring of the speed deviation can only be used in the following control modes:
• Servo control for synchronous motor (SM)
• Servo control for asynchronous motor (ASM)
Monitoring of the speed deviation is effective in the operating modes with contained speed
controller. It monitors the system deviation at the input of the speed controller (see blue arrow):
The error response set in the object 0x2D51:3
(or 0x3551:3 for axis B) is executed if
1. the set tolerance of the speed deviation (0x2D51:1
/ 0x3551:1) has been exceeded and
2. the duration of the exceedance is pending uninterruptedly as long as set in the 0x2D51:2 /
0x3551:2
object.
