4080 Incorrect configuration of indexing axis in MD %1
Parameters: %1 = String: MD identifier
Definitions: The assignment of a position table to an indexing axis or the contents of a position table contains an
error, or the length of a position table has been parameterized with 0.
Reaction: NC not ready.
Mode group not ready, also effective for single axes
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. 3 MD identifiers are output, depending
on the type of error.
1. $MA_INDEX_AX_ASSIGN_TAB (axis-specific MD 30500: The error is due to multiple assignment
of a position table (NCK MD 10910/10930 INDEX_AX_POS_TAB_n) to axes with different types
(linear/rotary axis).
2. $MN_INDEX_AX_POS_TAB_n (NCK MD 10910/10930): The contents of the displayed table n
contain an error.
- The entered positions must be arranged in increasing size.
- A particular position must not be set more than once.
- If the table is assigned to one or several modulo axes, then the contents must be within the 0 to <
360 degree range.
3. $MN_INDEX_AX_LENGTH_POS_TAB_n (NCK MD 10900/10920): The length of the displayed
position table n was specified with 0.
Program Clear alarm with the RESET key. Restart part program
Continuation:
4090 Too many errors during power-up
Definitions: More than <n> errors occurred during control power-up.
Reaction: NC Start disable in this channel.
Alarm display.
Remedy: Set the machine data correctly.
Program Switch control OFF - ON.
Continuation:
4100 System cycle time/scan time divider corrected for digital drive
Definitions: The machine data 10050 SYSCLOCK_CYCLE_TIME (system clock cycle) and/or MD 10080
SYSCLOCK_SAMPL_TIME_RATIO (dividing factor of the position control cycle for actual value
acquisition) have been corrected. The sampling cycle to which the digital drive is synchronized (drive
clock cycle) must be a multiple of 4, 8, 16 or 32 of 31.25µs.
The modifications were so made that, due to the selection of the system clock cycle time in MD 10050
SYSCLOCK_CYCLE_TIME, the programmable hardware divider 1 was readjusted in such a way that
the selected time and the basic drive cycle result in a 31.25µs grid. If this requirement is unfeasible
(e.g. because the system clock cycle is not a multiple of 31.25µs), the system clock cycle is
automatically increased until the basic drive cycle is in a 31.25µs grid.
The new value of the SYSCLOCK_CYCLE_TIME can be obtained from the MD 10050.
The position control cycle can be set with the following gradations:
- up to 4ms: 125µs step
- up to 8ms: 250µs step
- up to 16ms: 0.5ms step
- up to 32ms: 1ms step
Reaction: Alarm display.
Remedy: No remedial measures are required. The alarm display can be canceled with Reset.
Program Clear alarm with the Delete key or NC START.
