u Drive Functions
Each of the following functions must be enabled during start-up of the drive:
n Start and Stop the Drive
Set the Run Forward Command (BO 1) to run the drive in the forward direction. Set the Run
Reverse Command (BO 2) to run the drive in the reverse direction. Run/Stop Monitor (BI 1)
shows the current run status of the drive. Forward/Reverse Monitor (BI 2) shows the current
direction.
NOTICE: Damage to Equipment. Improper drive direction may damage HVAC equipment if parameter b1-04,
Reverse Enable, is set to 0 (Enable). Confirm proper motor rotation prior to connecting the load to the motor.
n Lock the Drive Panel
Locking the panel prevents the user from using the LOCAL/REMOTE and STOP keys locally
at the drive panel. Panel Lock (BO 10) can be commanded to lock and unlock the panel.
n Digital Inputs
Multi-Function Input S3 (BO 5) through Multi-Function Input S7 (BO 9) are physical digital
inputs on the drive. They can be set either by external devices, such as limit or pressure
switches, or by the network. Their function depends on how the drive has been programmed.
Refer to the drive manual section on Multi-Function Inputs (H1-03 through H1-07) for detailed
information on the use and programming of the multi-function inputs. The multi-function
input status can be monitored through Multi-Function Input 1 Monitor (BI 14) through Multi-
Function Input 5 Monitor (BI 19).The multi-function inputs can be set by both external devices
or over the network.
Note: The multi-function inputs can be set by both external devices or over the network. Use caution when
connecting the multi-function inputs to external devices to ensure correct system operation.
n Loop Gain
PI Proportional Gain (AO 4) and PI Integral Time (AO 5) are the gain and integral time
parameters used by the drive. The PI loop is structured differently than the Metasys loop.
Refer to the drive manual section on PID for information on how the PI loop functions.
