Bit 09, Selection of ramp 1/2Bit 09=‘0’ means that ramp 1 is active (3-40 Ramp 1 Type to3-47 Ramp 1 S-ramp Ratio at Decel. Start). Bit 09=‘1’ meansthat ramp 2 (3-50 Ramp 2 Type to 3-57 Ramp 2 S-ramp Ratioat Decel. Start) is active.Bit 10, Data not valid/Data validIs used to tell the frequency converter whether the controlword is to be used or ignored. Bit 10=“0” causes thecontrol word to be ignored, giving the opportunity to turnoff the control word when updating/reading parameters.Bit 10=“1” causes the control word to be used. Thisfunction is relevant, because the control word is alwayscontained in the telegram, regardless of which type oftelegram is used.Bit 11, Relay 01Bit 11=‘0’ Relay not activated. Bit 11 = ‘1’ Relay 01activated, provided Control word bit 11 has been chosen in5-40 Function Relay.Bit 12, Relay 02Bit 12=‘0’ Relay 02 has not been activated.Bit 12=‘1’ Relay 02 has been activated, provided Controlword bit 12 has been chosen in 5-40 Function Relay.Bit 13/14, Selection of set-upBits 13 and 14 are used to select one of 4 menu set-upsaccording to Table 4.9:Set-up Bit 14 Bit 131 0 02 0 13 1 04 1 1Table 4.9 Menu Set-upsThe function is only possible when Multi-Set-ups is selectedin 0-10 Active Set-up.NOTICEIn 8-55 Set-up Select a selection is made to define how Bit13/14 gates with the corresponding function on the digitalinputs.Bit 15 ReverseBit 15=‘0’ causes no reversing.Bit 15=‘1’ causes reversing.NOTICEIn the factory setting reversing is set to digital in8-54 Reversing Select. Bit 15 causes reversing only when Ser.communication, Logic AND or Logic OR is selected.4.4.1 Status Word according to FrequencyConverter Profile (STW)→Illustration 4.3 8-10 Control Word ProfileBit Bit value=0 Bit value=100 Control not ready Control ready01 Drive not ready Drive ready02 Coasting Enable03 No error Trip04 No error Error (no trip)05 Reserved -06 No error Trip lock07 No warning Warning08 Speed ≠ reference Speed = reference09 Local operation Bus control10 Out of frequency limit Frequency limit ok11 No operation In operation12 Drive ok Stopped, auto start13 Voltage ok Voltage exceeded14 Torque ok Torque exceeded15 Thermal ok Thermal exceededTable 4.10 Staus Word BitsExplanation of the status bitsBit 00, Control readyBit 00=‘0’ means that the frequency converter has tripped.Bit 00=‘1’ means that the frequency converter controls areready, but that the power component is not necessarilyreceiving any power supply (in the event of external 24 Vsupply to controls).Bit 01, Drive readyBit 01=‘1’. The frequency converter is ready for operation.Bit 02, Coasting stopBit 02=‘0’. The frequency converter has released the motor.Bit 02=‘1’. The frequency converter can start the motorwhen a start command is given.Bit 03, No error/TripBit 03=‘0’ means that the frequency converter is not infault mode.Bit 03=‘1’ means that the frequency converter is tripped,and that a reset signal is required to re-establish operation.Bit 04, No error/Error (no trip)Bit 04=‘0’ means that the frequency converter is not infault mode.How to Control MCA 122 Modbus TCP24 MG90P202 - VLT® is a protected Danfoss trademark44
