Page 21: Modbus Communication
OPERATING MANUAL OPERATING MANUAL 9.5.3.2 Modbus Communication A Modbus RTU protocol is available on all the fan models. The line must be connected to MODBUS-A, MODBUS-B and GND pins. There are two possible Modbus connections: 1) During the fan functioning through any RS-485 serial connection 2) With the driver powered off through an UART serial connection To connect the driver to a PC during the fan functioning, a USB to 485 converter can be used: K431F8. To connect OFFLINE the driver to a PC when the fan is powered off, a USB to UART converter can be used: K431A6 for 1-phase drivers. A MOLEX connector "1" is used to connect the cable to the driver. 1-phase Specifications and drivers can be downloaded from Nicotra Gebhardt website: https://www.nicotra-gebhardt.com 21/40 Rev. 0 - 11/12/2020... -
Page 22: Tachometric, Alarm And Filter Output
OPERATING MANUAL OPERATING MANUAL 9.5.3.3 Tachometric, Alarm and Filter Output The analogue output channel is configured, by default, to provide a tachometric output signal. The tachometric output is a 0 to 5V PWM waveform at 1KHz (for FDP 1.05kW -1-Ph only). when the speed is equal or higher than the speed min and it is 0% when the speed is lower. The device reading the output must be connected to TACHO\ALARM\FILTER pin and GND. The max current supplied of the output is 0.2mA. Remember that the Speed is 0 whenever the required speed is lower than Speed unless the fan is in the dragging Real phase. The same analogue output channel can be reconfigured, by changing the value in Holding Register 46 (see paragraph 16.3 at page 34), as a Digital Alarm Output (refer to chapter 17 and paragraph 17.4), or in one of the alternative alarm modes described in pa- ragraphs 11.1 and 11.2. -
Page 23: Speed Control
OPERATING MANUAL OPERATING MANUAL 10.1 Speed control 10.1.1 Analog speed control (INPUT TYPE = 1 Default factory setting) Through this setting the fan speed is proportional to the analog voltage input. The fan speed is limited by the Safe Operating Area, therefore, depending on the fan working point, the fan could be no more able to increase the speed coherently to the set voltage value. To avoid the loss of signal dynamic, a speed limit rescaling is necessary by modifying the value of the Max Speed Holding Register 2. It is also possible to rescale the min Speed by modifying the Holding Register 1. The analog signal can be read from the Input Register 14. For more details refer to the ANNEX -> Analog Signal Considerations. The MAX and min speed default values are in function of the fan sizes. -
Page 24: Speed Control Curves: Examples
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 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. 10.2.1 Analog asynchronous emulation (INPUT TYPE = 7) Through this setting the slip is proportional to the analog voltage. 10.2.2 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. 10.2.3 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 25: Asynchronous Emulation Curves: Examples
OPERATING MANUAL OPERATING MANUAL 10.2.4 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. 10.3 PID closed control loop 10.3.1 Modbus temporary ref. PID closed control loop (INPUT TYPE = 11) In this mode the PID reference is defined by modifying the Holding Register 66. -

Page 27: Soft Start
OPERATING MANUAL OPERATING MANUAL 11.2 Soft start In the following paragraph the starting phase of a fan is shown. • The first phase when the fan receives a command to start running is the ALIGNMENT. During this phase the driver aligns the rotor. • The second phase is the dragging phase, where the fan gradually increases its speed to the minimum in open loop. In this phase the current and speed values present in the Input Register can’t be taken in consideration. • The last phase is the closed loop where the sensorless control is active and from the minimum speed to the target speed the fan accelerates with different ramps basing on the fan size and the wheel inertia. The acceleration and deceleration values are different and to avoid overvoltage alarm or loss of synchronism alarm, the deceleration is always lower. During the ALIGNMENT and DRAGGING phases a Loss of Synchronism alarm could occur if there is a condition of wrong rotor starting position or wrong position estimation during the open loop phase. This is not a blocking alarm; therefore the fan stops and auto-restarts after few seconds. -
Page 28: Other Variables
OPERATING MANUAL OPERATING MANUAL 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. 14. DERATING AND OVERHEATING PROTECTIONS 14.1 Driver overheating: DERATING When the temperature of the driver components overtakes a defined temperature threshold, the performance is automatically reduced to decrease the heating. It is possible to check in real time the temperature by reading the Input Register 15. If it is not possible to reach a steady thermal equilibrium, the driver shuts down. The protection acts limiting the current to the motor. In this condition the driver goes in alarm (see chapter 17). Once the temperature on the driver decreases under 75°C, the alarm is automatically reset. 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 17). -
Page 29: Master & Slave Mode
OPERATING MANUAL OPERATING MANUAL 15. MASTER & SLAVE MODE A Master & Slave connection is necessary when the fans have to operate in parallel and in any Constant-Airflow mode, or under control of the internal PID regulator. Having two or more fans self-controlling independently, while operating in parallel, can make the system unstable. A Master & Slave connection is neither needed nor recommended when the fans in parallel are runnig in any speed-control mode, even if under control of a common external PID regulator. MASTER SLAVE MASTER SLAVE 15.1 Master and Slave 0-5V PWM out (for 1.05 kW 1-phase only) This single-phase driver has a tachometric output ranging from 0 to 5V and a special configuration must be set on the slave fan for a Master&Slave connection. It is possible to drive two fans in a master and slave configuration by setting the MASTER in any preferred mode and the SLAVE in Master&Slave mode only. The SLAVE operating mode must be changed (INPUT TYPE = 3). The MASTER must have the Holding Register 46 set at 0 = TACHO. 16 COMMUNICATION When trying to enter a value in any holding register, the value is not overwritten if the new value is outside the load boundaries. - Page 30 OPERATING MANUAL OPERATING MANUAL Supported Function: Read Holding Registers Read Input Registers Write Single Holding Register Modbus Communication Timeout With this feature it is possible to stop the fan when the communication is lost, after a period of time set in the Holding Register 56. The register can be set to: No Communication Timeout Time expressed in seconds, therefore it is possible to set 1 to 32767 from 1sec to 9h 6m 8 sec When the timeout occurs, the driver goes in alarm condition and the communication must be restored and the alarm must be cleared. The alarm is indicated in the Input register 17 with the value of 255 (0xFF).

Page 31: Temporary Holding Register
OPERATING MANUAL OPERATING MANUAL 16.1 Temporary holding register The Holding Register 66 is a special register used in each operating mode for setting the speed, the airflow, the slip and the PID reference. It is not a physical register and it can be written, but it is not possible to read its value. The setting remains active until the fan is powered on. If the fan is powered off but there is a residual charge, the microcontroller of the driver is still functioning. Therefore, if it is powered on in this situation the value set through the register 66 is still active. 16.2 Fixed holding register The drivers Holding Registers permanently stored into the EEPROM are 64, but only 26 registers are modifiable by the end user (see the table in the following page). - Page 32 OPERATING MANUAL OPERATING MANUAL Holding Register 0: RESET [Adim] This register can be used to reset the fan by writing the value 1 on it.
