MD
This parameter set acts only on the first measuring system (mounting on motor side), i.e. a
variable gear ratio may be required. The second measuring system in normally a direct
measuring system (mounting on load side). Between this measuring system and the
movements to be measured, there is normally a fixed gear ratio which can be taken into
account, as with previous software versions, by means of pulse/path evaluation.

MD
If the function "Extended parameter set switchover" is not active, then the following value
settings are fixed, i.e. the values given above are irrelevant:
Axis:
3032* ... 3060*
= 1 (Number of teeth, motor)
3064* ... 3092*
= 1 (Number of teeth, spindle)
3096* ... 3124*
= 0 (Zero mark compensation +)
3128* ... 3156*
= 0 (Zero mark compensation -)
3160* ... 3184*
= MD 220* (backlash compensation)
The backlash compensation value of the 1st parameter set is
activated in all parameter sets.
Spindle:
2400* ... 2407*
= 1 (Number of teeth, motor)
2408* ... 2415*
= 1 (Number of teeth, spindle)
2416* ... 2433*
= 0 (Zero mark compensation +)
2434* ... 2441*
= 0 (Zero mark compensation -)
