For absolute servo, host controller can access absolute motor position by communication(rs232/485) or
DI/DO. ISA-7 absolute system supports two types of position value, pulse and PUU(Pulse User Unit).
In the first time of operation, the servo emerges AL033, because coordinate system is not established,
the warning will continue until initialization finished. If the battery exhausted or power interruption, the
coordinate may lost, it may lead to AL033 too. In absolute system, maximum and minimum position is
