4.8.2.2 Fault reaction
Via parameter
Fault Reaction 1143, you can define the behavior of the drive when
the hardware limit switch is reached.
Fault Reaction 1143
Function
0 - Disabled No evaluation of hardware limit switches.
1 - Error-Switch-Off
Factory setting. The drive is stopped and error mes-
sage "F1447 Pos. HW Limit Switch" or "F1448 Neg. HW
Limit Switch" is output.
2 - Shutdown, Error
The drive is stopped at the current deceleration ramp
1)
and error message "F1447 Pos. HW Limit Switch" or
"F1448 Neg. HW Limit Switch" is output.
3 -
Emergency-Stop,
Error
The drive is stopped at the current emergency ramp
2)
and error message "F1447 Pos. HW Limit Switch" or
"F1448 Neg. HW Limit Switch" is output.
10 - Warning
Via parameter
Application Warnings 273, warning mes-
sage "A 0008 HW-LIM CW" is output when the positive
HW limit switch is reached, "A 0010 HW-LIM CCW" is
output when the negative HW limit switch is reached.
For parameter
Create Appl. Warning Mask 626, "13 -
Warning pos. HW-Limit-Switch" and "14 - Warning neg.
HW-Limit-Switch" are available.
1)
Deceleration ramp:
In JOG mode, the drive is stopped based on the values for parameters
Decelera-
tion
1177, Ramp Fall Time 1178.
When motion blocks are processed, the drive is stopped based on the values for
Deceleration 1206 and Ramp Fall Time 1207.
2)
Emergency ramp: The drive is stopped based on the value for parameter Emer-
gency ramp
1179.
