7-82 Operating Modes MPH-02, MPB-02, MPD-02

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

This actual position value is set by the command "set absolute

measuring" or by "drive-controlled homing procedure" for the actual

position value that has been selected in the synchronization mode that

was set. If, for example, the operating mode "phase synchronization with

virtual master axis, encoder 1" has been set, P-0-0753, Position actual

value in actual value cycle will change by analogy with S-0-0051,

Position feedback 1 value. The range of feedback 1 value, however, is

limited to S-0-0103, Modulo value. The homing of S-0-0051, Position

feedback 1 value will cause P-0-0753, Position actual value in actual

value cycle to be set to the same value as S-0-0051, Position feedback

1 value. The position status of the actual position value in the actual value

cycle can be taken from bit 4 of parameter P-0-0089, Status word for

synchronous operating modes.

The actual value cycle is calculated

• when progressing to operating mode in the transition command from

phase 3 to 4

- or -

• by starting the command P-0-0071, C3100 Recalculate actual value

cycle for recalculating the actual value cycle in phase 4 when a

parameter, that was used for calculating the actual value cycle, was

changed in phase 4.

Note: At the start of command C3100 the status bits in S-0-0403,

Position feedback value status and the status bit in

P-0-0089, Status word for synchronous operating modes

(bit 4) are cleared. After the position data reference has been

successfully established, the bits are set again.

The actual value cycle is calculated in dependence of bit 4 of parameter

P-0-0155, Synchronization mode.

With bit 4 = 0 in P-0-0155 the actual value cycle is determined in

dependence of P-0-0752, Load revolutions per actual value cycle

slave axis.
