How to parameterise the master frequency output:
1. As encoder type ( C00422 ), select "5: LF In/Out" to activate the master frequency output.
2. Set the number of increments for the digital frequency output in C00030/1 .
The number of increments determines after how many output increments a zero pulse will
be generated. Each zero pulse defines a covered "revolution" of the rotary transducer
simulated by the digital frequency output.
3. Set the desired function of the digital frequency output in C00540 (see the following
section).
Selecting the function of the digital frequency output
Function ( C00540 ) Info
1: Off Digital frequency output not active
• The frequency "0" is output at the digital frequency output.
• All tracks remain on the level output last.
• After switching on the controller, the tracks A, B and Z are set to HIGH level.
2: DFIn The TTL input signals at X8 are connected through to the digital frequency output.
3: MotorSpeed Output of the motor encoder
• The angle of rotation derived from the motor encoder in [increments] is output as
frequency signal after being evaluated with the number of increments set in C00030/1 .
4: LoadSpeed Output of the load encoder
• The angle of rotation derived from the load encoder in [increments] is output as
frequency signal after being evaluated with the number of increments set in C00030/1 .
5: Resolver Output of the resolver angle
• The angle of rotation derived from the resolver input in [increments] is output as
frequency signal after being evaluated with the number of increments set in C00030/1 .
• It is irrelevant for the output whether the resolver input is used as load encoder, motor
encoder or not at all within the motor control.
6: DigIn 1/2 Output of the digital inputs DI1/DI2
• The angle of rotation derived from the digital inputs in [increments] is output as
frequency signal after being evaluated with the number of increments set in C00030/1 .
7: AFB input Output of a speed signal of the application
• The speed signal defined via the nOut_v input of the LS_DFOut system block is integrated
and output as frequency signal after being evaluated with the number of increments set
in C00030/1 .
