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.

System cycle time/scan time divider corrected for digital drive

Definitions: MD10050 $MN_SYSCLOCK_CYCLE_TIME (system clock cycle) and/or MD10080
$MN_SYSCLOCK_SAMPL_TIME_RATIO (division factor of the position control cycle for actual value acquisition)
have been corrected.
The new value of the system clock cycle can be taken from MD10050 $MN_SYSCLOCK_CYCLE_TIME.
For PROFIdrive:
The sampling cycle to which the digital drive is synchronized (drive clock cycle) is largely determined by the cycle spec-
ifications of the STEP 7 project (above all the PROFIBUS and PROFINET cycle grids).
An additional, independent cycle division factor is not required for the actual value acquisition (that means MD10080
$MN_SYSCLOCK_SAMPL_TIME_RATIO = 1 usually applies).
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.

IPO cycle changed to %1 ms

Parameters: %1 = String (new IPO cycle time)
Definitions: The IPO cycle divisor was set to a value which was not an integral multiple of the position control cycle divisor. The
divisor (MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO) was increased.
For PROFIBUS/PROFINET: MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO has been modified because of the
modified DP cycle in the SDB (MD10050 $MN_SYSCLOCK_CYCLE_TIME).
Reaction: Alarm display.
Remedy: MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO has been modified.
Program Clear alarm with the RESET key. Restart part program

PLC cycle increased to %1 ms

Parameters: %1 = String (new PLC cycle time)
Definitions: The PLC cycle divisor was set to a value which was not an integral multiple of the IPO cycle divisor. The divisor
(MD10074 $PLC_IPO_TIME_RATIO) has been increased.
For PROFIBUS/PROFINET: MD10074 $PLC_IPO_TIME_RATIO has been modified because of the modified DP
cycle in the SDB (MD10050 $SYSCLOCK_CYCLE_TIME).
Reaction: Alarm display.
Remedy: MD10074 $MN_PLC_IPO_TIME_RATIO has been modified.
Program Clear alarm with the RESET key. Restart part program
