Alternate Time
This function changes (alternates) the running order (priority) of the drives/motors based on the time set in
parameter AP1-56 (Alternate Time). The amount of time (before alternation occurs), can be viewed at AP1-58 (Alt
Timer Disp). When the AP1-58 time reaches the set time AP1-56, run priority is changed and the drives are
alternated.

Time is counted by the Lead (+) drive when one or more motors are in operation including the Lead (+)
drive. If all drives are running, alternation does not occur. At least one drive must be idle (not running) and
cannot be in standby mode (Priority “0”). If priority of any drive is “0”, the drive is not included in the
alternating sequence. Additionally, alternation is performed after each Stop or Sleep of the system (when all
drives are stopped).
When the alternating sequence AP1-49 (ALT Sequence) is set to either “
FILO or FIFO”
, priority is changed
by one step.
◼
Example: When priority is 1,2,3,4 (shown as 4321 at AP1-45), Drive ID 1 is the first priority, first to run.
After alternating, the priority is changed to 3,2,1,4 making Drive ID 1 the second priority and making
Drive ID the first priority.
When the alternating sequence AP1-49 (ALT Sequence) is set to “
Op Time Order
”, priority is based on
the operating time of each drive. The drive with the lowest operating time is set to the first priority and the
drive with the highest operating time is set to the last priority. If the operating time of each drive is the same
when alternation occurs, priority is not arranged.
◼
The following is an example of alternating and how priority is arranged.
◆
When priority is 1,2,3,4, (shown as 4321 at AP1-45) and only Drive ID 1 is operating, it has the
longest operating time. Drive ID’s 2, 3 and 4 are in stopped state. After alternating, the new
priority will be 2,3,4,1 (shown as 1432). Drive ID 1 was set to last priority and remains stopped.
Drive ID 2 starts operating as it is now the first priority.
