UC800 AFD Operation
AFDJ-SVU01D-EN 49
UC800 Interface to Adaptive Frequency
Drive
Communications between the UC800 and the AFD are
handled via the Machine Bus (“M-bus”) connected to the
RS-485 AFD Comm Interface module. Signals digitally
sent over the M-bus include start, stop, speed change, and
drive faults.
At start of the compressor motor a signal corresponding to
the starting frequency (38 Hz) is sent to the drive.
The digital speed signal is set-up such that the AFD
operates over a 38–60 Hz frequency range.
AFD faults are sent over the M-bus to the UC800 controls
for communication on the Tracer AdaptiView display.
High Pressure Cutout—The inverter accepts a NC HPC
switch. In the event of a chiller high pressure condition, the
HPC switch opens, the drive shall shut down and de-
energize the motor.
Output contacts are required to control the load of the
refrigerant/oil pump motor and the cooling circulating
pump. The contacts are Normally Open, and closed when
the AFD energizes the motor.
