SINUMERIK 840D sl/840D/840Di/810D Diagnostics Guide (DA), 08/2005 Edition
Definitions: The monitoring cycle MD 5002: MONITOR_CYCLE_TIME must be identical for both axes
on 2-axis modules.
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: Modify MD 5002: MONITOR_CYCLE_TIME for both axes.
Program Con-
tinuation:
Switch control OFF - ON.
310706 Axis %1 drive %2 maximum working speed invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Because of the high maximum motor speed in the drive MD 5401: DRIVE_MAX_SPEED
and the speed controller cycle in MD 5001: SPEEDCTRL_CYCLE_TIME sufficiently high
speeds can occur to cause a format overflow.
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: Reduce the maximum working speed in MD 5401: DRIVE_MAX_SPEED or set a smaller
speed controller cycle in MD 5001: SPEEDCTRL_CYCLE_TIME.
Program Con-
tinuation:
Switch control OFF - ON.
310707 Axis %1 drive %2 STS configuration of axes differ
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of the control block MD 5003: STS_CONFIG (STS configuration) must
be identical for both axes on 2-axis modules.
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: Check drive MD 5003: STS_CONFIG (STS configuration) and set the bits for the two
axes of the module so that they are the same. (Do not change the default setting - this
corresponds to the optimum configuration).
Program Con-
tinuation:
Switch control OFF - ON.
310708 Axis %1 drive %2 number of encoder marks of measuring system invalid
Parameters: %1 = NC axis number
