NB6 23 X SAFTY PRECAUTIONS - Request Thank you for purchase of "SJ-LW (LonWorks Option)". [. . . ] (1) nviInvSetFreq = 0x7FFF (Default) It is possible to set the request speed by using ratio of Nominal Frequency (Refer to chapter 5. 4. 6) or Nominal Speed (Refer to chapter 5. 4. 5). (2) nviInvSetFreq = 0 to 400, It is possible to set 0 to 400Hz to nviInvSetFreq directly. 9 CHAPTER 5 LONWORKS COMMUNICATION FUNCTION Setting ratio Request speed AUTO(Invalid) Stop state Initial value AUTO(Invalid) Stop state Note: Requested speed will not be greater then the value defined by nciMaxSpeed (Refer to chapter 5. 4. 8) or less then the value defined by nciMinSpeed (Refer to chapter 5. 4. 7). *1 nviDrvSpeedScale = 100, Direction: Forward = -100, Direction: Reverse = When a value in nviDrvSpeedScale is set any value except for 100 and ­100, it becomes the stop command (Run: Deceleration stop, Stop: Maintain to stop). Default value: Default value is AUTO (state = 0xFF). This network variable input may use the Receive Heartbeat function depending on if Receive Heartbeat function is setup for use. Scaling: See chapter 6. 1. 4 5. 2. 4 Speed Setpoint Scaling (SNVT_lev_percent nviDrvSpeedScale) This input network variable provides scaling for nviDrvSpdStpt. For example if nviDrvSpeedStpt value is 100% and nviDrvSpeedScale value is -150%, then actual speed setpoint value is -150% meaning reverse 1, 5 times nominal speed. The requested speed will not be greater than the value defined by nciMaxSpeed or less than the value defined by nciMinSpeed. Depending on Drive Speed Setpoint, behavior of Speed Setpoint Scaling will be changed. (1) nviInvSetFreq = 0x7FFF(Initial value) It prescribes the scaling for Drive Speed Setpoint (Refer to chapter 5. 2. 2). nviDrvSpeedScale = 100, Direction: Forward = -100, Direction: Reverse = When a value in nviDrvSpeedScale is set any value except for 100 and ­100, it becomes the stop command (Run: Deceleration stop, Stop: Maintain to stop). Example (1): nviInvSetFreq = 0x7FFF For example if nviDrvSpeedStpt value is 100% and nviDrvSpeedScale value is -150%, then actual speed setpoint value is -150% meaning reverse 1, 5 times nominal speed (Refer to chapter 5. 3. 6). Also refer to 6. 1. 4. 10 CHAPTER 5 LONWORKS COMMUNICATION FUNCTION Example (2) : nviInvSetFreq = 0 to 400 When nviInvSetFreq is at 60Hz and nviDrvSpeedScale is 100%, the inverter is in forward run at 60Hz. Valid Range: -163. 84 to163. 83% Default Value: Is defined by nciDrvSpeedScale (Refer to 5. 4. 14). Scaling: See chapter 6. 1. 4 5. 2. 5 Emergency Override (SNVT_hvac_emerg nviEmergOverride) When EMERG_SHUTDOWN command is inputted, the inverter executes the deceleration stop and also the value in EMERG_SHUTDOWN is supported but the other values are not supported. (Deceleration time is dependant on Ramp Down Time (Refer to chapter 5. 4. 10)) Value Definition Contents Support 0 EMERG_NORMAL Yes 1 EMERG_PRESSURIZE No 2 EMERG_DEPRESSURIZE No 3 EMERG_PURGE No 4 EMERG_SHUTDOWN Yes 5 EMERG_FIRE No 0xFF EMERG_NUL No 11 CHAPTER 5 LONWORKS COMMUNICATION FUNCTION 5. 3 Output Network Variables - nvo's 5. 3. 1 Node Object Status (SNVT_obj_status nvoObjStatus) This nvo reports node object status. Identifier Invalid_request Report_mask Comm_failure In_alarm Disabled Manual_control Status The node has been asked for an unsupported request. See digital operator value at A001 (should be 02 to avoid manual control to be set) and A002 (should be 01 to avoid manual control to be set). Manual_control will be set if option-board isn't in control over one parameter. It will be set if NviObjRequest have received a RQ_MANUAL_CTRL request. If another identification number then 0 and 1 have been set in request by SNVT nviObjRequest. The request will not be carried out. Invalid ID 5. 3. 2 Drive Status (UNVT_sj300 nvoDrvStatus) This output network variable provides the status of the drive. The first three bytes will be mapped directly from the information received at address 0xFFFF8E10 in the SJ300/L300P. [. . . ] Setting nciWriAdr to 0xFFFF (65535 decimal) and writing any value to nciWriValue will save parameters to SJ300/L300P EEPROM. NOTE : The inverter will be stopped using the normal stop ramp before saving, so it's recommended to send the save command only when inverter already is stopped. The values set from option board will now remain the same after a boot sequence of the inverter. There is no need to use the saving to EEPROM function when parameters are set from the digital operator since they always are saved between power-cycles. 6. 3 Optionboard Error handling If there is no response from SJ300/L300P on the serial channel in three messages in a row communication is believed to be down.
