Selection Info
1 Digital frequency output is inactive
• "0" frequency is output a the digital frequency output.
• All tracks remain on the level output last.
• After the controller is switched on, the tracks A, B, and Z are set to HIGH level.
2 The digital frequency input X9 is directly connected to the digital frequency output.
Note:
Due to the direct connection between input and output, sensors are no longer required.
• The zero pulse offset (C13052
/ C14052) is without function.
• The frequency limitation (C13053
/ C14053) is without function.
• The zero track is only output if connected to X9.
• The display parameters for the actual values (speed, frequency, position) are not updated
(remedy: use display parameters of the digital frequency input).
•The outputs DFOUT_dnActualPos_p and DFOUT_dnActualSpeed_s of the system block
LS_DigitalFrequencyOutput are not updated.
3 Output of the motor encoder
• The angle of rotation in [increments] derived from the motor encoder is output as a frequency
signal after being evaluated with the set number of increments (C13051
/ C14051).
• The output signal is integrated to a position value via a counter and made available to the
application via the output DFOUT_dnActualPos_p of the system block
LS_DigitalFrequencyOutput.
4 Output of the load encoder
• The angle of rotation in [increments] derived from the load encoder is output as a frequency
signal after being evaluated with the set number of increments (C13051
/ C14051).
• The output signal is integrated to a position value via a counter and made available to the
application via the output DFOUT_dnActualPos_p of the system block
LS_DigitalFrequencyOutput.
5 Output of the resolver angle
• The angle of rotation in [increments] derived from the resolver input is output as a frequency
signal after being evaluated with the set number of increments (C13051
/ C14051).
• The output signal is integrated to a position value via a counter and made available to the
application via the output DFOUT_dnActualPos_p of the system block
LS_DigitalFrequencyOutput.
• It is irrelevant for the output whether the resolver input is used as a load encoder, motor encoder,
or not used at all for the motor control.
