6-5-4 Latch mode
In the latch mode (Type_Code = 5
h), the motor actual position can be latched and read at the input timing of trigger
signal without initializing position information.
While in the latch mode, Busy as latch process remains 0. This means that any other command e.g. parameter command
can be executed while in the latch mode. However, commands that initialize position information, such as reset command
and homing command (except for latch mode) forcibly cancel the established latch mode.
Note: In Latch trigger signal, Latch detection time has a difference with Logical rising edge and Logical falling edge.
This servo driver is recommended for Logical rising edge wfich set a-contact.
6-5-4-1 Starting/canceling latch mode
To start/cancel the latch mode, use Type_Code.
2CHs can be put in the latch mode at the same time.
