SAMI G S 8.5 Checking Selected Application Macro Parameters Selected macro parameters have default settings which suit most purposes. The pa- rameters which are not included in the Appli- cation Macro retain the factory settings. If it is necessary to adjust the parameter values, refer to the instructions in Sections 7 and 9. Use the parameter list in the Application Macro Manual (or Table on pages 33 - 36) to record your settings. Only selected macro parameters will be displayed (e.g. Parame- ter group 25 for PI-Control and group 28 for PFC-Control. 10. If everything is operating normally, turn off SAMI and disconnect it from the mains. Note!
Wait at least 5 minutes af- ter the display readout has disap- peared before taking any further action within the SAMI. (For fault tracing information, refer to Section 10 page 71) 8.7 Keypad Control Test With Motor 1. Connect the motor to the SAMI (after first making sure that the SAMI is discon- nected from the mains). 8.6 Keypad Control Test Without Motor 1. If the motor is connected to the SAMI, disconnect it (after first making sure that the SAMI is disconnected from the mains). 2. Connect the SAMI to the mains and switch power on. 3. Set the DIRECTION (par. 11.8) to REQUEST. 4. Select Operating Data, 9 CONTROL PLACE, KEYPAD R1 (see Section 7, Control and Parameter Logic). 5.
Return to para. 1 SAMI OUTPUT FREQ. 2. Connect the SAMI to the mains and switch power on. 3. Select Operating Data, 9 CONTROL PLACE, KEYPAD R1 (see Section 7, Control and Parameter Logic). 4. Select KEYPAD REF 1. Choose 0.5Hz. Warning! If rotation direction is critical, do not increase speed reference more than necessary after start to make sure the motor is running in the right direction. If the rotation direction is not correct swap 2 of the motor cable connections. 6. Give a start command by pushing The run status indicator on the display should show "I". 5. Give a start command by pushing . 6. Check the Operating Data parameter values for normal operation. 7.
Use key to change the rotation direction. The rotation direction display should change accordingly. 8. Change to the Setting Mode and control the reference frequency. Return to Dis- play mode by pressing 7. Change to Setting Mode and increase the reference. Verify that the frequency is increasing. Increase the frequency to 50 Hz. Return to Display Mode. 9. Check the Operating Data parameter values. 8. If external controls, analogue outputs, relay outputs, PI-controller or other control equipment are used in the application, check that they operate correctly. Parameter 7, SAMI OUTPUT VOLTAGE should increase with the frequency.
Pro- grammed maximum voltage is reached at the field weakening frequency (default is 50 Hz). 9.Test the functioning of the emergency stop (if installed). 32
