VARIABLE SPEED DRIVE (VSD)
6.1 VSD OPERATION
Generally the WSPC functions operate in the same
manner for VSD machines as with non-VSD
machines. When a VSD compressor is connected to
the WSPC, the program provides additional
functionality for monitoring and controlling VSD
operation. This section defines those additional
WSPC functions that are available for VSD
compressors.
6.2 COMPRESSOR DATA TAB
When a VSD machine is connected to the controller,
additional VSD related parameters are displayed at
the Compressor Data screen. See Figure 6-1. The
data shown indicate current, recent and lifetime
performance of the VSD compressor package.
Lifetime data are averages or totals since the time
the compressor was commissioned. Recent data are
averages and totals since the last reset. Current data
show instantaneous flow rate and power estimates of
the compressor package.
