8.11 Gearing
8.11.1 Overview
Electronic Gearing, EEO, Master-Slave
AKD2G offers up to 5 feedback channels, which may be used as the
command source for electronic gearing or EEO (Emulated Encoder Output)
or Master-Slave.

8.11.2 Input - Electronic Gearing
AKD2G offers up to 5 feedback channels. Any of these channels may be used as the gearing command source. The
gearing source is selected for each axis using AXIS#.GEAR.FBSOURCE. Refer to the WorkBench Online Help
Electronic Gearing for more information.
8.11.3 Output - Emulated Encoder Output (EEO)
The drive calculates the motor shaft position from the cyclic- absolute signals of the commutation feedback,
generating incremental-encoder compatible pulses or CW/CCW signals or Pulse/Direction signals from this
information.
The resolution and the index (zero) position can be set in WorkBench. The outputs are driven from an internal supply
voltage. Refer to the WorkBench Online Help for more information.
When using a multispeed resolver (more than 2 poles) as commutation feedback, the EEO will create only
one zero pulse per each mechanical revolution of the motor. The zero pulse is dependent on the motor
starting position!
EEO1-4 are NOT compatible with 24V signal level and will be damaged if connected to +24V!
Technical characteristics connector X22, EEO2
Pulse outputs on the connector X22 are 2 signals: track A and B with 90° phase difference (i. e. in quadrature, hence
the alternative term “AquadB” output).

Max. number of connected slaves is determined by the loading characteristics of the slaves. 32 slaves can be
driven if the input impedance of the bias network is 10kΩ and only one slave has a DC termination resistor.
