Setting: C0540 = 0
ƒ The analog signal at the input DFOUT−AN−IN is converted into a
frequency and output to X10.

Example:
The input signal at DFOUT−AN−IN amounts to 50 %, the number of
increments corresponds to 2048 inc/rev. (C0030 = 3) and the maximum
speed (C0011) is set to 3000 rpm.

Generating an index pulse
An artificial index signal can be generated for the output frequency.
1. Set the input DFOUT−SYN−RDY = HIGH.
– 360° later, a LOW−HIGH edge generates the index pulse.
– Then a zero pulse is generated every 360 ° according to C0030.
2. If necessary, shift the zero pulse by up to 360 ° (65536 inc = 360 °) via
C0545.
Setting: C0540 = 1
ƒ The speed signal at the input DFOUT−DF−IN is converted into a
frequency and output to X10.

Example:
The input signal at DFOUT−DF−IN amounts to 3000 rpm, the number of
increments corresponds to 2048 inc/revolution (C0030 = 3).
