Overview of Alarms
SIMODRIVE alarms
300704 Axis %1 drive %2 speed controller cycle time invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: In the drive MD 1001: $MD_SPEEDCTRL_CYCLE_TIME.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
The following values are permissible:
611D control module Speed controller cycle
- Standard control as 1-axis: >= 125 µs
- Standard control as 2-axis: >= 500 µs
- Performance 1-axis: >= 62.5 µs (MSD >= 125 µs)
- Performance 2-axis: >= 125 µs
- 810D: >= 312.5 µs
- MCU: >= 125 µs
- Performance 2, 1-axis: >= 31.25 µs
- Performance 2, 2-axis: >= 62.5 µs
Program Switch control OFF - ON.
Continuation:
300705 Axis %1 drive %2 position controller cycle time invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The monitor in the 611D module has detected a position controller pulse rate which is beyond the
permissible limits. The conditions for a permissible position controller pulse rate are:
1. Minimum cycle period: 250µs (810D 312.5µs)
2. Maximum pulse rate: 4 s
3. The position controller pulse rate must be a multiple of the speed controller cycle given in the drive
MD 1001: $MD_SPEEDCTRL_CYCLE_TIME.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Change the position controller pulse rate on the NC.
Program Switch control OFF - ON.
