Info

On units equipped with optional supply fan and/or exhaust fan VFDs, the fan speed is controlled by a 3-phase VFD. The supply fan VFD is located in the supply fan section (030-050 size units) or mixing box section (055-100 size units) behind an access door. For 075-100 size units with optional high-capacity power exhaust or return/exhaust fan, the exhaust fan VFD is located in the mixing box section behind an access door. The P-Series units use ABB VFDs. The VFDs communicate to the ComfortLink MBB over the local equipment network (LEN). The VFD speed is controlled directly by the ComfortLink controls over the LEN. The interface wiring for the VFDs is shown in Fig. A and the terminal designations are shown in Table A. The VFD has a keypad display panel that can be used for Service Diagnostics and setting the initial VFD parameters required to allow the VFD to communicate on the LEN. Additional VFD parameters are set by the ComfortLink controls and sent to the VFD over the LEN at power up of the VFD. The VFD faults can be reset with the VFD keypad or through the ComfortLink controls (AlarmsR.CUR =Yes). Table B outlines the VFD parameters required to initialize communication over the ComfortLink LEN. These parameters must be set correctly for any communications to occur. These APPENDIX D — VFD INFORMATION Table A — VFD Terminal Designations 194 parameters come preset from the factory. If the VFD is replaced, these parameters must be set at the initial power up of the drive. This can be accomplished by running the Carrier Assistant through the VFD keypad (see START UP WITH THE CARRIER ASSISSTANT section), or setting each of the parameters individually. After the parameters in Table B have been set, the ComfortLink controls configure the additional parameters listed in Tables C and D automatically. These parameter configurations are sent to the VFD at every power up. The parameters listed in Table C have corresponding ComfortLink configurations (ConfigurationS.VFD and ConfigurationE.VFD). The parameters in Table D are hard-coded to be set as listed. After configuration Tables C and D have been sent to the VFD, the drive continues to send and receive information from the ComfortLink controls. This information is outlined in Tables E and F. Table E lists the information the VFD sends to the ComfortLink controls, and Table F lists the information the ComfortLink controls send to the VFD. These tables are updated at every scan the ComfortLink controls perform of the LEN. This occurs approximately once every second.
