Input I15 Special START input
♦ Input for fast and defined starting of positioning process.
♦ The "Fast start" function is switched on using P18=2 or 3 (when using P18=3, the
PLC data interface is also switched on).
♦ When I15="0", all positioning processes (POSA, POSR) are blocked.
♦ When I15="1", positioning processes are started. I15 has no influence during a
positioning process.
♦ A positioning process interrupted with STOP is continued using START (I5="1")
and "Fast START" (I15="1").
♦ The reaction time of I15 before the start of the positioning process is 1.5 ms.
♦ I15 has no effect in speed control mode.
Note! The START signal (I5) is not replaced by I15; after STOP, a START
signal (I5) is required to start the program and for WAIT START.
8.6.1.6 Synchronous STOP using I13
I13 in the standard model (COMPAX XX00) provides a STOP function with which
you can stop and idle multiple COMPAX units simultaneously, regardless of the
current speed.
P219=128 or 135 enables the synchronous stop via I13 (P219 bit 7 36 =1).
I13="1": Normal mode
I13="0": Synchronous STOP is activated.
After I13="0"
♦ the drive is stopped using P10 as the absolute ramp time and
♦ the ramp type selected via P94 37 .
♦ Error message E08 is output,
♦ O1 is set to 0 and
♦ the ready contact is opened.
While I13=0, any further positioning attempts are negatively acknowledged with
E08. No negative acknowledgment comes from HEDA.
Synchronous STOP function using I13 is only available on the standard unit
(COMPAX XX00).

Using I13 for stop bring both axes to a stop simultaneously.
