3.2.25 Digital frequency output (DFOUT)

3−68

EDSVS9332S−EXT EN 2.0

3.2.25.4 Encoder simulation of the resolver

Set C0540 = 2 or C0540 = 3 (depending on the desired generation of the zero track)

l The function is used when a resolver is connected to X7.

l The encoder constant for output X10 is set in C0030.

Generating a zero pulse in resolver zero position (C0540 = 2)

The output of the zero pulse with regard to the rotor depends on how the resolver is mounted to the

motor.

l The zero pulse can be shifted by +360° via C0545 (65536 inc = 360°).

Generating an external zero pulse (C0540 = 3)

An artificial zero pulse can be generated for the output frequency.

l The function is activated through a LOW−HIGH edge at the input DFOUT−SYN−RDY.

l A LOW−HIGH edge at terminal X5/E5 causes the generation of the zero pulse after 360°.

– After this, every 360° a zero pulse is generated according to the setting in C0030.

l The zero pulse can be shifted by +360° via C0545 (65536 inc = 360°).

) Note!

The procedure for generating an artificial zero pulse must be repeated after every

mains switching and after every setting of C0540 = 3.

3.2.25.5 Direct output of X8

(C0540 = 5)

l The input signal at X8 is electrically amplified and directly output.

l The signals depend on the assignment of the input X8.

l C0030 and C0545 have no function.

l The zero track is only output if it is connected to X8.

3.2.25.6 Direct output of X9

(C0540 = 4)

l The input signal at X9 is electrically amplified and directly output.

l The signals depend on the assignment of the input X9.

l C0030 and C0545 have no function.

l The zero track is only output if it is connected to X9.

) Note!

For directly outputting X8 or X9 to the digital frequency output X10 the function

block DFOUT does not need to be entered into the processing table.
