Examples of Input Signal Allocation
The procedure used to allocate sequence input signals is described using the /S-ON signal
as a typical example.
Pn50A.1
Setting
Description Remarks
0 Inputs the /S-ON signal from the SI0 (CN1-40) input terminal. Signal Polarity: Normal
1 Inputs the /S-ON signal from the SI1 (CN1-41) input terminal.
Example: Servo-ON signal (/S-ON) is valid when
low (ON).
2 Inputs the /S-ON signal from the SI2 (CN1-42) input terminal.
low (ON).
3 Inputs the /S-ON signal from the SI3 (CN1-43) input terminal.
4 Inputs the /S-ON signal from the SI4 (CN1-44) input terminal.
5 Inputs the /S-ON signal from the SI5 (CN1-45) input terminal.
6 Inputs the /S-ON signal from the SI6 (CN1-46) input terminal.
7 Sets /S-ON signal so that it is always valid. Set the Servo-ON signal (/S-ON) so that is is al-
ways valid or always invalid.
8 Sets /S-ON signal so that it is always invalid.
ways valid or always invalid.
9 Inputs the /S-ON signal from the SI0 (CN1-40) input terminal. Signal Polarity: Reversed
A Inputs the /S-ON signal from the SI1 (CN1-41) input terminal.
Example: Servo-ON signal (/S-ON) is valid when
high (OFF).
B Inputs the /S-ON signal from the SI2 (CN1-42) input terminal.
high (OFF).
C Inputs the /S-ON signal from the SI3 (CN1-43) input terminal.
D Inputs the /S-ON signal from the SI4 (CN1-44) input terminal.
E Inputs the /S-ON signal from the SI5 (CN1-45) input terminal.
F Inputs the /S-ON signal from the SI6 (CN1-46) input terminal.
Note
Settings 9 through F can be used to reverse signal polarity.
If reverse polarity is set for the Servo-ON, Forward Run Prohibit, or Reverse Run Prohibit signals, safe opera-
tion may not occur when troubles, such as broken signal lines, occur. You must confirm operational safety if
setting reverse polarity is necessary for one or more of these signals.
As shown in the table above, the /S-ON signal can be allocated to any input terminal from
SI0 to SI6. /S-ONis alwaysinput when Pn50A.1 isset to 7, and an external signal line would
therefore not be needed because the Servopack will determine whether the servo is ON or
OFF.
The /S-ON signal is not used when Pn50A.1 is set to 8. This setting is meaningful only in
the following instances.
·
When the factory set input signal are to be replaced by another input signal.
·
The signal must be left ON (low level) during normal operation to make the signal valid
when OFF (high level) when forward run prohibit (P-OT) and reverse run prohibit
(N-OT) are input. The input terminal signal line must be left ON even in system configu-
