8-8. Stopping Pulse Cutput
The pulse output stop function is used to terminate the drive in execution.
The pulse output stop function includes the slow stop function, immediate stop function, LIMIT slow
stop function, and LIMIT immediate stop function.
◆ When STATCS1 PCWT EXT PCLSE = 1 (external pulse being output), the stop command is disabled.
(1) Slow stop function
The slow stop function is enabled when STATCS1 PCWT STBY = 1 or DWIVE = 1.
When an active slow stop command is detected, drive pulse output in execution is slowed down to the
end speed and is stopped, and then the drive ends.
STATCS1 PCWT SSEWD is set to 1 upon detection of an active slow stop command.
The slow stop function includes the following slow stop commands:
・ SLCW STCP command
・ SLSTCP signal that uses general-purpose input or SEWSCW signal as the SLSTCP function
・ SS0, SS1, and DALM signals that set the input function for slow stop
・ Comparator output of various counters that set the stop function for slow stop
◆ When the slow stop command is detected when STBY = 1, the slow stop function works after DWIVE is
set to 1.
◆ If the slow stop command is active immediately before STBY is set to 1, the drive ends.
◆ The slow stop function is disabled when STBY = 1 while interpolation drive is stopped after
execution.
(2) Immediate stop function
The immediate stop function is enabled when STATCS1 PCWT BCSY = 1.
When an active immediate stop command is detected, the drive in execution is forcibly terminated.
STATCS1 PCWT FSEWD is set to 1 upon detection of an active immediate stop command.
The immediate stop function includes the following immediate stop commands:
・ FAST STCP command
・ FSSTCP1 signal
・ FSSTCP2 signal
・ SS0, SS1, and DALM signals that set the input function for immediate stop
・ Comparator output of various counters that set the stop function for immediate stop
◆ When the 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.
◆ The data setting command being executed is not forcibly terminated even if an immediate stop
command is detected.
The FSEWD flag remains unchanged.
