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.
