12.27.2 Parameter set switchover with SW 4 and higher (option)
" Ratio" parameter group
The "Ratio (R)" parameter group contains the following parameters:
Axis
1stPaSe 2ndPaSe 3rdPaSe 4thPaSe 5thPaSe 6thPaSe 7thPaSe 8thPaSe
Parameter
Number of teeth, motor 3032* 3036* 3040* 3044* 3048* 3052* 3056* 3060*
Number of teeth, spindle 3064* 3068* 3072* 3076* 3080* 3084* 3088* 3092*
Zero
mark compensation + 3096* 3100* 3104* 3108* 3112* 3116* 3120* 3124*
Zero mark compensation - 3128* 3132* 3136* 3140* 3144* 3148* 3152* 3156*
Backlash compensation 220* 3160* 3164* 3168* 3172* 3176* 3180* 3184*
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.
Spindle
1stPaSe 2ndPaSe 3rdPaSe 4thPaSe 5thPaSe 6thPaSe 7thPaSe 8thPaSe
Parameter
Number of teeth, motor 2400* 2401* 2402* 2403* 2404* 2405* 2406* 2407*
Number of teeth, spindle 2408* 2409* 2410* 2411* 2412* 2413* 2414* 2415*
Zero
mark compensation + 2416* 2417* 2418* 2419* 2430* 2431* 2432* 2433*
Zero mark compensation - 2434* 2435* 2436* 2437* 2438* 2439* 2440* 2441*
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 -)
