4.7 Compressor shutdown
The user has the possibility to perform an immediate shutdown or a controlled shutdown. By setting
the compressor Enable register [100] to Disabled, while the speed demand is greater than 0, the
drive will perform an immediate stop. Otherwise if the user sends a Disable command as well as 0
speed demand (insert 0 in Compressor Speed Demand register [101]), the drive will issue a
controlled stop. During the controlled shutdown, if the speed is lower than 3600 rpm the drive will
automatically decelerate towards 0 with more than 1000 rpm/s.
However, if the speed is higher than the platform speed (3600 rpm) it will decelerate with a default
rate of 200 rpm/s until it reaches the platform speed, then decelerate automatically with more than
1000 rpm/s. The deceleration rate may be configured through register [210] in the range of 30 to
600 rpm/s.
