2.1 Function list
Description
This function uses the servo motor encoder to
configure semi closed loop systems.
This function uses the load-side encoder to
configure fully closed loop systems.
This function performs homing once, and
thereafter does not require homing at every
power-on.
Description
This function uses LSP (Forward rotation stroke
end) and LSN (Reverse rotation stroke end) to
limit the travel interval of the servo motor.
The command pulse train form can be selected
from among three different types.
This function sets the rotation direction of the
servo motor without changing the command
polarity.
This function performs positioning control with
the value obtained by multiplying the position
command from the upper controller by a set
electronic gear ratio.
This function sets the time constant of
acceleration and deceleration.
This function performs smooth acceleration and
deceleration.
This function limits the servo motor torque.
This function limits the servo motor speed in the
torque control mode.
