Quick stop
● The motor and brake output are switched off without a group fault.
● "Quick stop" has priority over "Motor CW" and "Motor CCW".
● The input action responds to the active edge of the input signal, which means that
deactivation is possible when the static input signal "Quick stop" is present.
● The input trigger is canceled by removing the "Motor CW" and "Motor CCW" control
commands or using "Disable quick stop" (in the process image).
Example 1:
Digital input 1 signal = retentive/edge-triggered
①
Motor is switched on by "Motor CW".
②
Motor is switched on by "Motor CW", then switched off by the rising edge at digital input 1 (parameterized to input
action1 = Quickstop). By revoking the "Motor CW" command, the Quickstop function is reset.
③
Motor is switched on by "Motor CW", then switched off by the rising edge at digital input 1. By setting Quickstop
disable, the Quickstop function is reset and the motor runs "CW" again until the "Motor CW" command is revoked.
④
Motor is switched on by "Motor CW", then switched off by the rising edge at digital input 1. By setting Quickstop
disable, the Quickstop function is reset and the motor runs "CW" again. Although the static digital input signal 1
(DI2) is still present, the motor continues to run and is only reset by revoking the "Motor CW" command.
Reason: The input action is edge-triggered.
⑤
Motor is switched on by "Motor CW" and continues to run uninterrupted since Quickstop disable continuously
overwrites the edges of the signal of digital input 1 (DI2).
