$MN_POSCTRL_SYSCLOCK_TIME_RATIO
Factor for position- -control cycle
Min. input limit: 1
Protection level: 7/2
The position control clock cycle is entered as a multiple of the time units of the basic
system clock cycle SYSCLOCK_CYCLE_TIME.
The default setting is "1". This means that the position control clock cycle corresponds to
the basic system clock cycle SYSCLOCK_CYCLE_TIME.
Setting values > 1 involves computation time for processing the additional timer interrupts
by the operating system and should only be used in cases where a task exists in the
system that should run faster than the position controller clock cycle.
For systems with PROFIBUS- -DP connection, this MD represents ratio between the
PROFIBUS- -DP clock cycle and position controller clock cycle.
$MN_IPO_SYSCLOCK_TIME_RATIO
Factor for interpolator clock cycle
Min. input limit: 1
Protection level: 7/2
The interpolator clock cycle is entered as a multiple of the time units of the basic system
clock cycle SYSCLOCK_CYCLE_TIME.
It is only permissible to set integer multiples of the position controller clock cycle (set using
POSCTRL_SYSCLOCK_TIME_RATIO). Values, that do not represent an integer multiple
of the position controller clock cycle are automatically increased to the next integer multiple
of the position controller clock cycle before they become effective (at the next boot).
In this case, Alarm 4102 "IPO cycle increase to [ ] ms" is output.

$MN_IPO_CYCLE_TIME
Interpolator clock cycle
Min. input limit: - -
Protection level: 7/2
Interpolation time
Displays the interpolator clock cycle time (this cannot be modified !).
Internally, this is formed from the machine data SYSCLOCK_CYCLE_TIME and
IPO_SYSCLOCK_TIME_RATIO.
