Check and ensure that the EMC conditions are complied with.
Replace the hardware
Check the drive checksums
Clear the alarm with the RESET key. Restart the part program.
Axis %1 hardware encoder fault of the safety-relevant actual value
%1 = axis number
The encoder evaluation signals a hardware fault. Causes could be dirt
in the optical encoder evaluation or problems associated with the signal
transfer.
Alarm display
In addition, a STOP F is initiated, that can result in the subsequent
Alarm 27001 with fault IDs 0, 27023 and 27024. Alarm 27001 with fault
ID 0 can be prevented using the alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL greater than or equal to 1).
Check and ensure that the EMC conditions are complied with.
Replace the hardware
Clear the alarm with the RESET key. Restart the part program.
Stop A initiated for at least one axis
This alarm only indicates that Stop A has been initiated in at least one
axis and power on is required to acknowledge the alarm. The alarm is
output if the alarm priority function was activated in MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL.
Alarm display
Interface signals are set
"Pulse cancellation" is initiated for the axis involved.
Locate the cause of the error by evaluating additional alarm messages
Power-down the control and power-up again
Wait for Motor Module for at least one axis
Alarm when booting as long as the Motor Module of at least one axis is
still not ready for SI. When booting, communications to the Motor
Module have still not been established as the safety functions for at
least one axis are still not available.
The alarm display can be set in MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL (MD < 3) in such a way that
it can be individually displayed as to whether communications have
already been established for each axis.
