(3) LIMIT slow stop function
The LIMIT slow stop function is enabled when STATCS1 PCWT STBY = 1 or DWIVE = 1.
The LIMIT slow stop function includes the following LIMIT slow stop commands:
・ CWLM and CCWLM signals that set the input function for LIMIT slow stop
・ Stop at the SCFT LIMIT position by the SCFT LIMIT function
◆ When the slow stop command is detected when STBY = 1, the LIMIT slow stop function works after
DWIVE is set to 1.
◆ If the LIMIT slow stop command is active immediately before STBY is set to 1, the drive ends.
◆ If the slow stop command for the CWLM or CCWLM signal is active immediately before STBY is set to 1
during interpolation drive, the drive ends regardless of the drive direction.
◆ The LIMIT slow stop function is disabled when STBY = 1 while interpolation drive is stopped after
execution.
CWLM signal
: When the active level is detected during drive in the + direction, the drive pulse
●
output in the + direction is slowed down and stopped to end the drive.
This signal is invalid
during drive in the - direction.
CCWLM signal : When the active level is detected during drive in the - direction, the drive pulse
●
output in the - direction is slowed down and stopped to end the drive.
This signal is invalid
during drive in the + direction.
Cpon detection of an active CCWLM signal, STATCS1 PCWT SSEWD and LSEWD are set to 1.
(4) LIMIT immediate stop function
The LIMIT immediate stop function is enabled when STATCS1 PCWT STBY = 1 or DWIVE = 1.
The LIMIT immediate stop function includes the following LIMIT immediate stop commands:
・ CWLM and CCWLM signals that set the input function for LIMIT immediate stop
◆ When the LIMIT immediate stop command is detected while drive pulse output is active, pulse output
ends after the active width of the pulses being output is secured.
◆ For 2-axis interpolation drive, the function is enabled even when STBY = 1 after drive execution is
stopped.
The function is enabled while the DEWD signal at STBY = 1 is in <servo support> or while the EWD
PCLSE drive at STBY = 1 is in DELAY.
CWLM signal
: When the active level is detected during drive in the + direction, the drive pulse
●
output in the + direction is immediately stopped to end the drive.
This signal is
invalid during drive in the - direction.
Cpon detection of an active CWLM signal, STATCS1 PCWT FSEWD and LSEWD are set to 1.
CCWLM signal : When the active level is detected during drive in the - direction, the drive pulse
●
output in the - direction is immediately stopped to end the drive.
This signal is
invalid during drive in the + direction.
Cpon detection of an active CCWLM signal, STATCS1 PCWT FSEWD and LSEWD are set to 1.
