Page 13: Product Description
OPERATING MANUAL OPERATING MANUAL 7. PRODUCT DESCRIPTION The Fans of series DDMP combine high energy efficiency and low noise level. Thanks to the “EC” (electronic commutation) motors, their electronics integrate speed control and protecting system. This reduces the number of different components required to provide these functions, compared to fans with traditional motors. The main feature of EC-motor is operating without slip losses, which allow consuming significantly less power than conventional AC motors. This occurs at all speed levels, especially with partial load operation. The EC complete drive system (i.e. the combination of the permanent-magnet motor with its electronic driver) has a much higher energy efficiency, in comparison with a drive system based on a conventional AC motor. Energy saving system • High efficiency EC-motor • Compact and streamlined motor design • High intensity neodymium magnets • No obstruction of intake due to build-on control unit - less aerodynamic losses General Features • Sensorless control • Simple installation due to plug and play • IP 54 for complete drive • Designed for double inlet fans Interface • Analogue interface for speed control • Full MODBUS interface compliancy High efficiency of direct driven centrifugal fan •... -

If it is not necessary turning on/off the fan with an external switch, a jumper can be inserted between clamps +24V and ENABLE. In case this jumper is not included, the fan will not start. -
Page 38: Aux Power Supply (For Ddmp 2.65Kw - 3-Ph Only)
OPERATING MANUAL OPERATING MANUAL If the transducer has its own PID control, the signal must be connected to the standard ANALOG INPUT. 9.6.3.5 +24V AUX Power supply (for DDMP 2.65kW - 3-Ph only) The +24V output can supply a max current of 50mA and it is able to drive the Nicotra Gebhardt pressure transducer (code K43198). Use an available ground pin on the board for powering devices. 9.6.3.6 +12V AUX Power supply (for DDMP 2.1kW - 1-Ph only) The 12V power supply can be used to provide power to the pressure transducer K43198, where a 24V supply is not available. An auxiliary power supply of 12V is available on the 2.1kW Single-Phase drivers. The max current absorbed must be lower than 200mA. Use an available ground pin on the board for powering devices. This power is not stabilized and it decreases when the current absorption exceeds the above indicated limit. - Page 39 OPERATING MANUAL OPERATING MANUAL 9.6.3.7 Relay (for DDMP 2.65kW - 3-Ph only) A relay is available on the Three-Phase drivers.

- Page 40 OPERATING MANUAL OPERATING MANUAL 10. OPERATING MODES AND SETTING OPTIONS Depending on the fan model, there are 4 possible Operating Modes and for each mode 3 possible Setting Options. Modbus Control Speed Control (Temporary setting) Constant PID Closed OPERATING Airflow Control SETTING MODES Sensorless Loop OPTIONS Asynchronous Emulation Analog Signal Fixed Modbus Control (Permanent setting) The operating modes and the setting options can be chosen by modifying the INPUT TYPE Holding Register 34.
- Page 41 OPERATING MANUAL OPERATING MANUAL 10.1.4 Speed control curves: example The following figures show a set of performance curves at different speed settings limited by the fan max working limit curve (see paragraph 1.6). 10.2 Constant airflow 10.2.1 Analog constant airflow (INPUT TYPE = 4) Through this setting the constant airflow is proportional to the analog voltage input. Each fan has default lower and higher limit for the constant airflow curves that can be increased by modifying the Holding Register 42 and the Holding Register 43. The choice of reducing the Constant Airflow Range is depending on the user application and it is especially useful when the appli- cation must guarantee a defined minimum constant airflow. The selectable airflows are restricted to a minimum and/or maximum defined range for each fan size. The lower limit avoids big deviations from the constant airflow while the high limits are determined by the Safe Operating Area. 10.2.2 Modbus temporary constant airflow (INPUT TYPE = 5) Through this setting the fan runs at the constant airflow defined by modifying the Holding Register 66.
- Page 42 OPERATING MANUAL OPERATING MANUAL 10.2.4 Constant airflow curves: example The following figures show 6 constant airflow curves randomly chosen and the relationship between the voltage signal and the corresponding airflow. 10.3 Asynchronous emulation Through this mode there is the possibility to emulate the behavior of an asynchronous induction motor with a slip and a power limitation dependent on the load and speed (therefore there could be some differences from each size). The control is expressed in percentage instead of a defined measure unit. The lower is the slip the higher is the performance and vice versa. 10.3.1 Analog asynchronous emulation (INPUT TYPE = 7) Through this setting the slip is proportional to the analog voltage. 10.3.2 Modbus temporary asynchronous emulation (INPUT TYPE = 8) Through this setting the fan emulates an ACIM motor and the slip is defined by modifying the Holding Register 66. The setting is maintained meanwhile the fan is powered on and it is lost when the fan is powered off. 10.3.3 Modbus fixed asynchronous emulation (INPUT TYPE = 9) Through this setting the fan emulates an ACIM motor and the slip is defined by modifying the Holding Register 30.
- Page 43 OPERATING MANUAL OPERATING MANUAL 10.3.4 Asynchronous emulation curves: example The following figures show 5 curves with the following slip percentage: 100%, 80%, 60%, 40% and 20%. The slip has not a physical meaning and must be intended as a 100% full performance and 0% fan stop. 10.4 PID closed control loop Through this setting the fan can work in a PID closed control loop where the measured process variable is connected to the TRANS- DUCER INPUT that can be monitored through the Input Register 31. and it must be in the range of [0,10V]. The PID mode can be therefore used with temperature probes, pressure transducer, CO/ CO2 detectors, etc.
- Page 44 OPERATING MANUAL OPERATING MANUAL 10.4.1 Analog ref. PID closed control loop (for 3-phase only) (INPUT TYPE = 10) In this mode the PID reference is given by the analog signal present at the ANALOG INPUT that can be monitored through the Input Register 29. 10.4.2 Modbus temporary ref. PID closed control loop (INPUT TYPE = 11) In this mode the PID reference is defined by modifying the Holding Register 66. The value of the reference is expressed in steps of 0.1 Volt (therefore the register ranges from 0 to 100) The PID error is calculated in the following way: Error = (Modbus - ANALOG REG_66 Input 10.4.3 Modbus fixed ref.
- Page 45 OPERATING MANUAL OPERATING MANUAL 11. OTHER FEATURES 11.1 Filter alarm This feature is useful when the speed of the fan is not directly set by the user as fans set in Constant Airflow Asynchronous Emu- lation or PID mode. The alarm is active when a speed threshold is overtaken (5V or 10V depending on the fan model). To activate this feature, the Holding Register 46 must be set at value 2 and the required Speed Threshold value must be set into the Holding Register 55. The digital output of the driver changes its status (see above figure). 11.2 Out of functioning range alarm (for 1-phase - 1.05 kW only) The digital output of the driver is high when the low limit of the speed threshold is overtaken, and it returns low when the high limit of the speed threshold is overtaken. To activate this feature, the Holding Register 46 must be set at value 3 and the low value of the Speed Threshold must be set into the Holding Register 16. While the high value of the Speed Threshold must be set into the Holding Register 55. The digital output of the driver changes its status following the behavior of the above figure (a hysteresis of 50 rpm is present to avoid several output changes of status).
- Page 46 OPERATING MANUAL OPERATING MANUAL 11.5 Skip speed Range (for 3-phase only) This feature allows to skip the resonance frequencies of the fan installation. To activate this feature the Holding Register 32 must be set at the desired Avoid Range Start and the Holding Register 33 the desired Avoid Range End. This function should be avoided when used in close control loops application or unstable conditions of the fan could occur. 11.6 Soft start In the following paragraph the starting phase of a fan is shown. •...
- Page 47 OPERATING MANUAL OPERATING MANUAL 12.3 Output current limitation The drivers are set by factory default to the max peak current out that changes depending on the motor windings characteristics. During the functioning it is possible to read the peak motor current to the motor by reading the Input Register 12. It is possible to reduce the motor current by modifying the Holding Register 7. It is suggested to keep the motor current above 3500mA. 12.4 Input current limitation This feature is not available for DDMPs. 13. OTHER VARIABLES There are other variables that can be monitored for a safe use of the fan. 13.1 Bus voltage The BUS voltage is the DC voltage on the bus capacitors. The driver is continuously monitoring this voltage and will stop the motor in the event of under-voltage or over-voltage. The value can be monitored through the Input Register 9. 13.2 Motor voltage The motor voltage is the peak value of the phase voltage module. To know the rms line to line value, it must be multiplied by √3/2. The value can be monitored through the Input Register 13. 13.3 Enable Function (for 3-phase only) A safety enable function is available and it is active for the Operating Modes in the following table.
- Page 48 OPERATING MANUAL OPERATING MANUAL 14.2 Motor overheating: THERMAL PROTECTOR The motor is protected through one or more Thermal Protectors. If the motor temperature is too high, the thermal protector opens one phase and the driver recognizes the error and stops the fan (see chapter 18). The Motor Winding temperature and the driver derating are dependent on the fan size and on the fan working point. Therefore, it is possible that the fan could work at 50°C without a performance limitation.

The three-phase drivers have a tachometric output ranging from 0 to 10 V. The master can have any possible configuration, while the slave must be configured in Analog Speed Control only. The MASTER must have the Holding Register 46 set at 0 = TACHO. With three-phase drivers connected in a master & slave arrangement, DO NOT set the slave driver in Master&Slave mode: if the slave is set in Master&Slave mode, it runs at twice the speed of the master.

- Page 58 OPERATING MANUAL OPERATING MANUAL 18. ALARM HANDLING When a malfunctioning occurs, the driver has two possible behaviors depending on the cause of the alarm: The cause of the alarm is very dangerous -> The driver stops immediately. To restart the fan, once the BLOCKING problem has been corrected, it is necessary to reset the fan or power the driver off for 5 minutes. The cause of the alarm is contingent to a wrong setting or wrong working condition. The alarm indica- AUTO-RESTARTING tions are activated, but after some seconds the fan tries to restart automatically. 18.1 Monitoring The alarms can be monitored through three different ways: • Modbus Registers • Blinking LED • Digital Output 18.2 Modbus registers - Alarm description In the following table, the alarms and the values stored in the related Modbus Input Register 10 and Input Register 17 are indicated.
