◆ Elevator Emergency Stop
■ Start Condition for Elevator Emergency Coast to Stop
An emergency coast to stop is performed when the Up or Down command is cleared and all of the following conditions
are met.
• Parameter b1-03 (Stopping Method Selection) is set to 4.
• Parameter d1-18 (Speed Reference Selection Mode) is set to 0 or 3.
• Parameter b1-01 (Speed Reference Selection) is set to 1.
• The Up/Down command is cleared and U1-05 (Speed Feedback) is equal to or greater than S1-26 (Emergency Stop
Start Level).
■ Elevator Emergency Stop Timing Chart
Figure 4.23 and Figure 4.24 show timing charts for Elevator Emergency Coast to Stop and normal Ramp to Stop.
