Aluminium cables with cross-section above 35 mm must be connected by use of a AI-Cu connector. Page 21 4. Always comply with national and local regulations on min. Page 22 Always comply with national and local regulations on min. AKD V All units require a minimum space above and below the enclosure. Page 28 Touching the electrical parts may be fatal, even after the mains supply has been disconnected. Using AKD , V: wait at least 15 minutes.
Following these the frequency converter has been fitted in an installation guidelines is advised, where compliance with EN cabinet with an output contactor and connected , EN or EN First environment is Single-layer braided copper wire with varying percentage screen coverage. This is the typical Danfoss reference cable. Double-layer braided copper wire. For AKD The frequency converter has a high leakage V, AKD V current and must be earthed appropriately the cables must be fastened with screws.
Use earth terminal If the EMC specifications regarding emission are to be complied with, the motor cable must be screened, unless otherwise stated for the RFI filter in question. Page Electrical Installation - Brake Cable AKD In systems with motors connected in parallel, the electronic thermal relay ETR of the frequency converter cannot be used as motor protection for the individual motor. Consequently, additional motor protection is required, such as thermistors in each motor or individual thermal relays suitable for frequency converter use.
It is used for serial communication, terminals 68 and The switching position shown is the factory setting. Switch 1 has no function. Page 42 AKD Function 1 1 1 1 2 2 2 2 , , , , 1 1 1 1 3 3 3 3 Voltage supply to digital inputs Tightening-up torque: 0. The control panel is detachable and can - as an alternative - be installed up to 3 metres away from the frequency converter, e.
The voltage LED is activated when the frequency converter receives voltage, or 24 V external supply; The Certain parameters can be changed step by step or infinitely variably. This applies to Motor power parameter , Motor voltage parameter and Motor frequency parameter This parameter initialises all except: Operating data Page Application Configuration AKD Application configuration There is a choice of the following configurations: Using this parameter enables the choice of a - Speed control, open loop configuration setting of the frequency converter - Speed control, closed loop that fits the application in which the frequency - Process control, closed loop converter is to be active.
This means that AMA itself 2. Set motor nameplate data in parameters to does not supply any torque. Contact your Danfoss supplier. A relative Feedback reference is a percentage value Y of the sum of The feedback signal must be connected to a terminal the external references X. This percentage value on the frequency converter. Choose a suitable time constant in intermediate circuit voltage has dropped to a given parameter , Process PID Lowpass filter. In order to obtain the possibility of a quick discharge, Optimisation of the process controller the frequency converter requires an external 24 V DC The basic settings have now been made; If This function makes it possible to "catch" a motor Both directions is selected, the frequency converter will that is spinning freely and for the frequency converter first find out in which direction the motor rotates and to take control of the motor speed.
This function is used mainly for pumps and fans, since these applications Description: do not require an overload torque. If a stop command is active via terminal 18 and the frequency converter is not at the torque limit, The advantage of choosing a normal torque the motor will ramp down to 0 Hz.
An external control command that can be connected to terminal 16, 17, 19, 27, 29, 32 or However, [2] or [4] must be selected in parameter Function: This parameter defines the Setup number to control the functions of the frequency converter.
Analogue input 60 [mA] Select Download power-independent par. See page was made in parameter Motor voltage [V] states the voltage supplied Warning word 2. The present reference will be maintained. If the reference Function: signal is negative, the local reference will be set at 0.
This is where the desired function is to be selected if Local control has been chosen in parameter Page 67 AKD Function: 5. Adapt parameter The rated motor speed n is used i.
In most applications, setting. If using special motor characteristics a correct entering of motor parameters is change in parameter affects parameter Set the desired frequency. The frequency converter can also be programmed to give off a warning signal via one of the digital outputs, in which case the signal is given both for Motor thermal protection warning and for trip thermal warning. Speed control, open loop: Speed control, closed loop: See also parameter This Function: presupposes that the output current does not reach It is possible to define how the preset references the torque limit to be set in parameter This is where to set the torque limit for motor operation.
Page 76 AKD Description of choice: If a setting in parameters is changed, parameter is not automatically reversed The upper signal limit of the motor current, I , must HIGH to the factory setting. Function: In this and the following parameters it is possible to choose between the different possible functions related to the inputs on terminals The frozen motor frequency is 16 17 Freeze output Page 81 AKD message "external fault" on the display when the unit; however, it will still be possible to carry selected terminal is logic "0".
The alarm message will out data changes via the bus. Page 82 AKD Max. This is only used in Torque Scaling of the input signal is effected in control, open loop parameter for limiting the parameters and Selected if the max.
Page 83 AKD Terminal 60, min. If used as a digital output data value [0]-[65] , a 24 V DC signal is transmitted; if used as Out of feedback range, the feedback signal is outside an analogue output either a mA signal, a the range programmed in parameters and Page 30 AKD Term. No speed change Speed up Speed down Speed down Freeze reference can be changed even if the frequency converter has stopped. The reference will also be saved if the mains are disconnected.
Value: Par. Page 37 AKD Description of choice: Description of choice: The factory setting is Enable [1], which means that Quick regulation is obtained by a high gain, but the integration link is initialised in relation to the if the gain is too high, the process may become actual output frequency if either the current limit, the unstable due to overshoot.
Page 41 Status word, parameter Gives the present status word for the frequency converter in Hex. See Serial communication for the AKD Inverter temperature, parameter Gives the present inverter temperature on the frequency converter.
Page 44 AKD 5. The frequency converter automatically undertakes a test of the control card. If the frequency converter displays a fault code from , the control card test has failed. Change the control card to start up the frequency converter. AKD Volt All dimensions are in mm. The frequency converter is cooled by means of air circulation. For the unit to be able to release its cooling air, the minimum free distance above and below the unit must be minimum mm.
Page General Information About Electrical Installation AKD General information about electrical installation High voltage warning The voltage of the frequency converter is dangerous whenever the equipment is connected to mains. Incorrect installation of the motor or frequency converter may cause damage to the equipment, serious injury or death. Comply with the instructions in this manual, as well as national and local rules and safety regulations.
Please note that for the IT mains and the delta earth the mains voltage can exceed Volts between phase and earth. Terminal 97 connected to V-phase. Terminal 98 connected to W-phase. The direction of rotation can be changed by switching two phases on the motor terminals. RFI switch Parallel connection of motors Mains supply isolated from earth Page Motor Cables Load sharing [5]. Use 6.
The screen must be connected to the frequency converter chassis by means of a clamp. Normally, the screen must also be connected to the chassis of the controlling unit use the instructions for the unit in question. See parameter Relay output for programming of relay output. A warning will be shown on the display until the fault has Turn off the frequency If one of these failures occurs, please contact Danfoss.
