Settings for the homing procedure (P728-P731)
The HOME ramp setting (P729) is reduced to the lowest allowable setting to get the fastest HOMING
procedure possible. The HOME velocity setting, however, should never be very high to enable a precise
result of the homing procedure, and because the exact position is not known during homing, it is not
advisable to go with a very high velocity for safety reasons. The default setting of P730 at 100 encoder
revolutions per minute (approx 1/15
default homing type defined in P731 is also maintained.
The resulting homing sequence is illustrated below.
Programming positions (P737-P743)
The program positions the conveyor cart in front of the various inlets and outlets. Different acceleration
and deceleration is allowed between the different positions. An empty pallet cart can be accelerated as
fast as possible while this is not allowed when transporting a fully loaded pallet.
Different settings for each position are available because every position is programmed with its own
setting for ramp and velocity. The different positions are defined below.
