5. SIMULATOR ENCODER GROUP “E”.
EP1 O (F500) EncoderSimulatorPulsesPerTurn
Function: Number of pulses per rotor turn generated by the encoder simulator.
Valid values: 1..16360 (Integer)
Default value: 1250
EP2 O (F501) EncoderSimulatorI0Position
Function: Rotor position where the encoder simulator generates the home marker pulse (Io).
Valid values: 1..EP1 (Integer)
Default value: 1
EP3 O (F502) EncoderSimulatorDirection
Function: With this parameter the turning direction of the simulated encoder is selected.
This parameter may be modified with the "C" command from the "ddssetup".
Valid values: 0 and 1, clockwise and counterclockwise rotation respectively.
Default value: 0 (clockwise ).
EC1 O (F503) EncoderSimulatorSetI0
Function: The execution of this command sets the current rotor position as the home point (I
0
).
Available in the command menu of the programming module "DDS PROG MODULE"
as EncoderSimulatorFixI0Command .
