·Positioning data selection: (Reference value 77)
Positioning data operation and immediate value operation are switched over.
The positioning data can be switched at an arbitrary timing between the following: positioning within 15 points
with internal positioning data and positioning with immediate value data for frequent positioning data change.
If the EI signal is turned on, the positioning data is enabled.
if the EI signal is turned off, the immediate value data is enabled.
If no signal is assigned on the EI input terminals, it is always regarded as turning OFF.
。
·Broadcast cancel: (Reference value 78)
The command using the broadcasting method via Modbus-RTU communications is canceled.
The Modbus-RTU protocol can issue queries from the host controller, the master, to all the slave stations at
the same time. For example, if the servo has a five-axis structure (of A, B, C, D, and E-axes), the servo motor
drive at all the stations can be started with positioning simultaneously.
On the other hand, the Modbus-RTU protocol cannot perform the broadcast by allocating a group station no.
separately.
For example, if the servo has a five-axis structure (of A, B, C, D, and E-axes), the servo motor drive cannot be
started with positioning simultaneously by selecting the A-axis and the B-axis only.
Thus by using this function, the broadcast in a separate group station no. can be performed.
The broadcast enable/disable status can be switched using the broadcast cancel signal.
If no signal is assigned on the EI input terminals, it is always regarded as turning OFF.
Furthermore,
if the broadcast cancel signal “78” is assigned to the parameter EI always ON,the broadcast
function is kept disabled. (The query of broadcast is always canceled.)

Specify the number corresponding to desired function (0 to 78)
Specify the EI input signal that is always enabled after the power is turned on.
The normally open connect signal is always turned on. The normally closed connect signal signal is always
turned off.
Functions that may not be specified with a normally open signal include alarm reset, deviation clear and
free-run.
