7.5.44.4 Encoder simulation of the resolver
Set C0540 = 2 or C0540 = 3 (depending on the desired generation of the zero track)
•
The function is used when a resolver is connected to X7.
•
The encoder constant for output X10 is set in C0030.
Generating an index pulse in resolver zero position (C0540 = 2)
The output of the index pulse with regard to the rotor depends on how the resolver is mounted to the
motor.
•
The index pulse can be shifted by +360° via C0545 (65536 inc = 360°).
Generating an external index pulse (C0540 = 3)
An artificial index signal can be generated for the output frequency.
•
Set input DFOUT-SYN-RDY to HIGH.
•
360° later, a LOW-HIGH edge generates the index pulse.
– After this, every 360° an index pulse is generated according to C0030.
•
The index pulse can be shifted by +360° via C0545 (65536 inc = 360°).
7.5.44.5 Direct output of X8
(C0540 = 5)
•
The input signal at X8 is electrically amplified and directly output.
•
The signals depend on the assignment of the input X8.
•
C0030 and C0545 have no function.
•
The zero track is only output if it is connected to X8.
7.5.44.6 Direct output of X9
(C0540 = 4)
•
The input signal at X9 is electrically amplified and directly output.
•
The signals depend on the assignment of the input X9.
•
C0030 and C0545 have no function.
•
The zero track is only output if it is connected to X9.
Tip!
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.
