Inhibiting pulse train input setpoint (P-TRG)
Note
P-TRG in PTI control mode
Note that the function "inhibiting pulse train by P-TRG in PTI control mode" as described in
this section and the rest of the manual is reserved for future use.
The digital input signal P-TRG is the default connection of DI6 in the position control mode.
In the pulse train input position control mode (PTI), P-TRG is level sensitive and can be used
to allow or inhibit positioning operation according to pulse train input setpoint:
●
0: positioning according to pulse train input setpoint
●
1: inhibit pulse train input setpoint

DI parameterization.
•
The signal P-TRG is active only when the digital input signal SON is in OFF state.
•
When the signal P-TRG is active in the PTI mode or a compound mode with PTI, the
alarm A7585 occurs.
