If the start block of a switch-signal-dependent sequential block is an
absolute or relative positioning block, the drive positions at target position
if the switch signal for block advance is not received. The drive thus only
generates the message "end position reached" after the sequential block
chain is completed. If a switch signal is then applied, the drive will carry
out the sequential block.

Note: According to master
acceptance takes place by toggling bit 0 in S-0-0346 or by a 0-
