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

8.10.1 Emulated Encoder Output (EEO)
The drive calculates the motor shaft position from the cyclic- absolute signals of the com-
mutation 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 motors starting position!
EEO1-4 are NOT compatible with 24V signal level! Will be damaged if connected to +24V!
Technical characteristics X22, EEO2
Pulse outputs on the connector X22 are 2 signals, tracks A and B, with 90° phase difference
(i.e. in quadrature, hence the alternative term “AquadB” output).
RS-485, current 100 mA
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.
Max signal (channel) output frequency: 3 MHz
The pulses per revolution value is settable, pulse phase shift: 90°±20°
