Default 0x20000000 = 536870912 = 29bit  GXMMW_H
0x2000 = 8192 = 13bit  GXAMW_H
0x10000000 = 268435456= 28bit  GCMMW_H
0x1000 = 4096 = 12bit  GCAMW_H
0x80000000 = 2147483648 = 31bit ²  GBMMW_H
0x40000 = 262144 = 18bit  GBAMW_H
EEPROM Yes
Significance Total measuring range in steps optionally programmable.
Consequence: Number of revolutions = total measuring range / resolution
The maximum resolution (0x6502) must not be exceeded since otherwise the selected
total resolution range is too wide and will be rejected.
Values 1..n.. max. total measuring range in steps (0x 6502)
Entries ≠ default values are only effective with enabled scaling function (0x6000).
² with disabled scaling 32 bit
Writing in these object will clear any previously saved offset (0x6509, value = 0)
Important for multiturn encoder operation:
Continuous operation will be automatically supported where required.
Consequently, no specific relationship between total measuring range and measuring units per revolution
must be observed in the parameterization.
With enabled continuous operation and during power off, the encoder shaft may be turned up to ¼ of
the maximum permissible turns. Any excess turn may entail void position values which will be
signaled by a warning and call for a new referencing operation.
Non-continuous operation allows for an unlimited number of turns during power-off.
Proceed as below to find out whether your parameterization enables continuous operation:
 The „maximum possible number of turns“ provided by the encoder (depending on the configuration:
16 bits = 65536 or 13 bits = 8192) is multiplied by the parameterized measuring units per revolution.
 The result is devided by parameterized total measuring range.
 A remainder in the result (fractional digits) means continuous operation enabled.
Example: Parameterization with disabled continuous operation:
Max. possible number of turns 65536 (16 bits multiturn)
Measuring units per turn : 3600
Total measuring range 29.491.200 (8192 x 3600)
Calculation: 65536 x 3600 / 29.491.200 = 8 (no remainder)
Example: Parameterization with enabled continuous operation:
Max. possible number of turns 65536 (16 bits multiturn)
Measuring units per turn 3600
Total measuring range 100.000
Calculation: 65536 x 3600 / 100.000 = 2359 remainder 29600
