Gearbox synchronization techniques:
- When “Gearbox Ratio Modulation Source” is defined, the gearbox runs in frequency synchronization.
- Otherwise, the gearbox runs in frequence and phase synchronization. There are two possibilities to
define the gearbox ratio:
o If both Master Modulo (0x3911,0) and Slave Modulo (0x3927,0) are not at zero, then the
gearbox ratio is defined with Slave_Modulo/Master_Modulo.
o If Master Modulo = 0 or Slave Modulo = 0, then the gearbox ratio is defined with gearbox ratio
Num/Den (0x3921).

Default Value
0x00000000
This object allows connecting any 16-bit dataflow as a modulation signal applied to the current ratio set.
The modulation value is from 0 to 0x7FFF.
The structure of the entries is the following:
MSB
LSB
Index (16-bit)
Sub-index (8-bit)
0
Example:
0x3920,0 = 0x30F10200
connects analog input 1 as the ratio modulation signal.
