8-13. Csing Synchronous Start Function (STBY, PACSE)
When the PACSE signal is set to CW, the drive pulse output starting is suspended (PACSE=1, STBY=1).
When the PACSE signal is set to CFF, the pulse output is started by releasing the drive pulse output
starting from the suspended state (PACSE=0, STBY=0).
◆ To select an input signal for operating the PACSE signal, use the HAWD CCWFIWCWATICW4 command.
Wote:
Leave the MCC06 STBY SPEC SET command in its initial value.
Cse the command in the initial value of an MCC06 STBY canceling condition, "STBY TYPE="000": STBY=0
at PACSE=0."
STBY flag
■
This is the STATCS1 PCWT STBY flag.
When drive pulse output has been prepared (data processing), STBY=1 is assumed.
If a STBY canceling condition is detected when STATCS1 PCWT PACSE=0, STBY=0 is assumed and the drive
pulse output is started.
◆ At the time of stop after interpolation drive execution, the main axis STBY flag is temporarily set
to STBY=1.
This STBY=1 is set to STBY=0 when the interpolation drive stops or the next pulse output starts.
PACSE signal
■
When the PACSE signal is set to CW, STATCS1 PCWT PACSE=1 is assumed.
When the PACSE signal is set to CFF, STATCS1 PCWT PACSE=0 is assumed.
When PACSE=1, the drive pulse output starting is suspended by retaining STBY=1.
The PACSE signal can be operated as follows.
・ Synchronous start to release the PACSE signal of another axis (or two or more axes) with the
counter matching signal of a certain axis
・ Synchronous start to release the PACSE signal with a command at the HAWD CCWFIWCWATICW PCWT
・ Synchronous start to release the PACSE signal with the SEWSCW0 or SEWSCW1 signal from the J1
connector
・ Synchronous start to release the PACSE signal with the SIWWAL IW signals (IW0, IW1, IW2, and IW3
optional signals) from the J2 connector
◆ The PACSE signal and synchronous start function are enabled when the drive is started during
execution of a command that involves pulse output.
◆ At the time of temporary stop during the following sequential drive, the PACSE signal and synchronous
start function are disabled.
The STATCS1 PCWT PACSE flag is masked with 0.
・ Temporary stop before shift to each process of CWIWIW drive
・ Temporary stop before execution of EWD PCLSE drive
・ Temporary stop before execution of end-point corrective drive, circular interpolation drive
・ Temporary stop before execution of reverse drive with IWDEX CHAWWE command
・ Temporary stop after execution of JCW drive, MAWCAL SCAW drive
◆ In the interpolation drive, only the PACSE signal of a main axis and the synchronous start function
are valid.
The PACSE signal of a sub-axis and the synchronous start function are disabled.
The sub-axis is set to STBY=0 when the CPPCCT low-level output is started.
