Set a number corresponding to signal name at desired system parameter, so that the signal can be assigned to the terminal.
■ Setting example
Set “1” at the “system parameter 1” so that the terminal [CONT1] of the control input/output connector [CN1] functions as the input terminal
for the “Run command” [RUN] signal.
■ Duplicated allocation
For the control input terminals, a signal cannot be assigned to more than one terminal simultaneously.
However, only the following signals can be assigned to more than one terminal:
・Forced stop (10)
・Free-run (54)
・External fault input (34)
In case of “forced stop” and “external fault input”, the motor will stop forcibly if an input terminal is off.
In case of “free-run”, the motor will be in free-run status if an input terminal is turned on.
If the signals other than the above have been assigned to more than one terminal, a control signal error [CtE] will be detected when turning
on power supply again.
For the control output terminals, a signal can be assigned to more than one terminal simultaneously.
Each terminal goes on or off at the same timing.
■ Interrupt input (49)
Be sure to assign the interrupt input (49) to any one of the terminals [CONT1] to [CONT8].
In case it is assigned to [CONT9] through [CONT13], a control signal error [CtE] will be detected.
■ Always valid
The functions can be assigned to the terminals by setting a numerical value at the system para. 1 to 8.
Similarly, the assigned functions can be always valid by setting the function (signal) number at the system para. 87 or 88. (See 6.3.6.)
Remark : If a number has been assigned to system para. 1 to 8 and system para. 87, 88 simultaneously, a control signal error [CtE] will not
be detected.
The assigned signal is always effective.
