Description of I/O Signals

Command Pulse inhibit: Sequence input signal (Reference value 26)
The pulse input in the position control mode is enabled or disabled.
 Function
The command pulse is not accepted while the command pulse inhibit signal remains turned on.
 Parameter setting
To assign pulse command inhibit to a sequence input terminal, specify the corresponding value
("26") 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.
Accordingly, pulse input is always enabled while servo-on [S-ON] is turned on.
Command pulse ratio 1: Sequence input signal (Reference value 27)
Command pulse ratio 2: Sequence input signal (Reference value 28)
This is used if changing the command input pulse multiplication during position control.
This signal is enabled only when parameter PA1_01 (control mode selection) is set to "6"
(extension mode) or "7" (positioning function).
 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 on, position control on (only if PA1_01 = 6), and command pulse ratio 1 (2) on to
enable pulse train 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 input is enabled, the following functions
are not enabled: manual feed, homing, start positioning, interrupt positioning, positioning cancel
and pause, etc.
 Parameter setting
To assign the command pulse ratio 1(2) to a sequence input terminal, specify the corresponding
value ("27" or "28") 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.
