Synchronization Ranges

Synchronization in the

Command Value Cycle

DOK-INDRV*-MP*-02VRS**-FK01-EN-P

• operating mode: cam shaft with P-0-0755 ≠ 0

Actual value cycle with rotary modulo scaling and P-0-0155, bit 4 = 1

• operating mode: phase synchronization and

cam shaft with P-0-0755 = 0

Actual value cycle with linear modulo scaling and P-0-0155, bit 4 = 1

• operating mode: cam shaft with P-0-0755 ≠ 0

Actual value cycle with linear modulo scaling and P-0-0155, bit 4 = 1

With modulo scaling the range for synchronization can be set in

parameter P-0-0155, Synchronization mode.

• modulo range (S-0-0103)

• command value cycle

• division of the command value cycle

The distance to be traveled is then limited to this range.

The actual position value used for calculating the distance

must be unequivocal in the range in which synchronization is

to take place. The actual value cycle (P-0-0752) from which

the actual position value is derived must therefore be

determined in such a way that is a multiple of the

synchronization range.

By setting P-0-0750, Master axis revolutions per master axis cycle = 0

it is possible to select absolute handling of the master axis within a range

of ± 2048 revolutions.

The distance traveled during synchronization is the result of the difference

between synchronous position command value (+ S-0-0048, Position

command value additional) and the actual position value. The

synchronization distance is limited to the modulo command value cycle.
