8.23 Position tracking

Drive with odd-numbered gearboxes without position tracking

In this case, for each encoder overflow, there is a load-side offset of

3 encoder overflows, the motor and load zero position coincide again. The position of the load

can no longer be clearly reproduced after one encoder overflow.

If position tracking is activated via p0411.0 = 1, the gearbox ratio (p0433 / p0432) is calculated

with the encoder position actual value (r0483).

● Configuration via p0411

● Virtual multiturn via p0412

● Tolerance window for monitoring the position at power ON p0413

● Input of the measuring gear via p0432 and p0433

● Display via r0483

Commissioning the function

The parameters p0412 (Measuring gear, rotary absolute encoder, revolutions, virtual) and

p0413 (Measuring gear, position tracking tolerance window) can only be set via the parameter

Odd-numbered gears with position tracking (p0412 = 8)
