 Relevant description
(1) Change setting completion
The signal is turned on after the changing process is executed according to the immediate value
change signal, and it is turned off after the immediate value change command is turned off.
(2) Command position / command speed / ABS/INC (IQ area)
Each piece of data can be changed arbitrarily. The data in the IQ area at the timing of activating
edge of the immediate value continuation command is enabled. However, the ABS/INC signal
retains the state enabled at the activating edge of the start positioning signal.
(3) Immediate value continuation command
When the immediate value continuation command and the immediate value change command
are turned on simultaneously, priority is given to the immediate value change command.
(4) Positioning cancel / pause
The signal is enabled at an arbitrary timing.

Command pulse ratio 1: Sequence input signal (Reference value 27)

Command pulse ratio 2: Sequence input signal (Reference value 28)

Pulse input from a manual pulse generator or similar rotates the servomotor.
This signal is enabled only for LS type.
 Function
While the command pulse ratio 1 (2) is tuned on, pulse input is enabled. To perform pulse
operation, be sure to assign the command pulse ratio 1 or command ratio 2 to a CONT input signal
to turn it on.
Turn servo-on and command pulse ratio 1 (2) on to enable pulse operation.
If command pulse ratio 1 is turned on, the ratio set at PA2_54 (command pulse ratio 1) is enabled.
If command pulse ratio 1 is turned off, and command pulse ratio 2 is turned on, the ratio set at
PA2_55 (command pulse ratio 2) is enabled.
The result of the following equation becomes the encoder-equivalent pulse.
(Number of input pulses) x ((Numerator 0 to 3 of electronic gear ratio)/(Denominator of electronic
gear ratio)) x Command pulse ratio
While the command pulse ratio 1/2 is turned ON and pulse train input is enabled, the following
functionsare not enabled: manual feed, homing, auto start, interrupt positioning, positioning
canceland pause, etc.
 Parameter setting
If assigning command pulse ratio 1/2 ON to the IQ area (sequence input terminal), set values (27)
or (28) corresponding to the input terminal function setting parameter.
This signal is handled to be always turned off if it is not assigned to the sequence input terminal.
