Figure 39. General state diagram
NOTE!
When using VACON
®
NX series AC drives and option board in "PROFIdrive" mode, the stop
command always follows the configured stop mode and not the stop command given from fieldbus.
NOTE!
Quick stop only occurs if the application supports it. If the application does not support Quick
stop, a normal ramp stop is executed.
