Eliminated from:
EVS93xx-EI (Servo PLC V8.0)
EVS93xx-ET (Servo PLC V8.0 with technology function)
Behaviour of the new version?
If the speed filter (C0496=1) is activated the correct actual speed value is indicated via the MCTRL_nNAct_a system variable. With quick stop, the motor is decelerated along the set ramp.
What happens?
Although the motor rotates the MCTRL_nNAct_a system variable indicates 0 as actual speed value. Although a ramp time has been set a quick stop leads to a sudden stopping of the motor.
When does the problem occur?
The response described before occurs if the speed filter is activated (C0496=1).
Which products are affected?
EVS93xx-EI (Servo PLC V7.2 and lower)
EVS93xx-ET (Servo PLC V7.2 and lower with technology function)
Possible diagnostics?
None.
Short-term measures/recommendations?
Do not activate the speed filter.
Evaluation:
If the speed filter is activated (C0496=1) a speed value of 0 is indicated. The MCTRL_nNAct_v system variable is not affected by this function restriction.
