Acknowledging errors
There are two categories of errors that have to be acknowledged in different ways:
• Module error
• Channel-related errors
In order to find out which category the currently pending error belongs to, refer to the chapter
. The diagnostic bits are subdivided there into the above-mentioned categories.
Acknowledging module errors
Both motor channels have a "Reset" variable. Apply a positive edge to each "Reset" variable.
It is not sufficient to acknowledge the error on only one motor channel. The module error and the
disablement of both motor channels are only canceled when the error has been acknowledged on both
motor channels.
Even if a motor channel is not being used, the error must be acknowledged on this channel.
Acknowledge channel-related errors
Apply a positive edge to the "Reset" variable of the motor channel affected. The variable "Reset" is located in
the process data object "STM Control Channel
n
" (
n
= 1...2).
Troubleshooting
• If an error message persists after acknowledgement, the error has probably not yet been eliminated.
• To successfully acknowledge the error "Open Load", you must first set "Enable" to 0.
