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 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).

  • 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°
