2 Drive Functional Features
The FLN protocol built into the drive frequency converter allows programming of numerous features and monitoring of the drive via the serial bus and the standard
RS-485 port. The drive also has the capability to control closed or open loop systems on its own and has been designed specifically for HVAC applications. Always
accessible in real-time are the system status, what the motor and drive are doing, and if there are any problems. The drive continuously monitors all aspects of
motor and drive status and issues alarms or warnings for adverse conditions. The FLN interacts with the drive based upon a point map database and the selected
interface strategy. Many, but not all, drive features are accessible through the point map. See the Operating Instructions for more drive details. Table Point
Mapping lists the map points and Table Point database definitions supplies definitions. Below is a review of some frequently used drive features and the associated
point map numbers.
2.1.1 Drive Operation (F-64)
These points provide the FLN with operational status information such as output frequency, motor current, output voltage, power and energy. The run time in
hours that power has been supplied to the motor is also stored for display, along with cumulative energy used in kWh.
2.1.2 Motor and Drive Thermal Protection (15, 16, 18)
The motor and drive are protected against thermal overload. The percentage of thermal load is displayed. Point 18 indicates if either the motor or drive thermal
limit has been exceeded.
2.1.3 Set-up 1-4 and Day/Night operation (17, 29)
In the FLN system it is not recommended to operate in multible set-up. The drive should remain in Set-up 1 at all times.
The drive is capable of maintaining four independent program set-ups. Each set-up supports independent point map configurations. Seasonal changes, various
acceleration or deceleration rates, or other operation modes can be accommodated. Point 17 indicates which setup is active. The set-up change is programmed
through the drive’s keypad or digital I/Os. Day/night operation is implemented in the point map (29).
2.1.4 Current Monitoring and Limits (19)
The maximum current that the drive provides to the motor can be limited. This tends to limit the torque that can be produced by the motor. Data point 19 indicates
if the motor is operating at that current limit.
2.1.5 Direction of Rotation (XC-22)
The drive responds to serial commands to reverse direction of the motor. The drive can safely reverse motor rotation while in operation. Many applications benefit
from this ability, such as vane axial fans reversed for smoke extraction or cooling towers for deicing. par. O-54 Reversing Select, must be set to serial communication
for point 22 to command the feature.
2.1.6 Start/Stop (23)
To run the drive from the FLN or in Auto mode from the drive‘s digital control terminals, a start command must be given at data point 23. When a stop command
is given at this point, the drive will only run in Hand mode.
2.1.7 Ramp Select (24)
Datapoint 24 selects the active ramp.
