Overview of Alarms
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
The following values are permissible:
611D control module Current controller cycle
• Standard control as 1-axis: >= 125 µs
• Standard control as 2-axis: >= 125 µs
• Performance 1-axis: >= 62.5 µs
• Performance 2-axis: >= 125 µs
• 810D: >= 156.25 µs

• Performance 2: >= 31.25 µs
Program Con- Switch control OFF - ON.
tinuation:
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.
Reactions: - 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 Con- Switch control OFF - ON.
tinuation:
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.
