Page 2: General Description
1. Introduction FRECON MINITERMINAL - control pod for the FIA-L programmable speed drives combines keypad and display functions : • local/remote control selection • local control (run/stop, forward/reverse, output frequency control resolution : 0,01Hz) • drive parameter values adjustment and display (LCD screen) •... - Page 3 4. Operational status indication Four red LEDs above the keypad indicate the status of the drive. - indicates status "RUN" or "STOP", i.e. the activation of the output power bridge light on : the output power bridge is active (status "RUN") light off : the output power bridge is inactive (status "STOP") - indicates actual control mode light on : local (keypad) control mode...
- Page 4 5.2. Control mode selection key Two modes are available : • local (keypad) control indication LOC : light on • remote control; without using keypad indication LOC : light off NOTE : - During initialization after energising the drive, the remote control mode is automaticaly selected as the active control mode.

Page 5: Control Modes
6.2. LOCAL CONTROL (keypad) In the local control mode the drive is fully operated by the control pod FRECON MINITERMINAL. The local control keys enable to start and to stop the drive, to change the direction of rotation, to set the output frequency reference FSET, or to control directly the actual output frequency FOUT in the full range 0-125 Hz with 0.01 Hz resolution,... - Page 6 7. Displayable values and adjustable drive parameters table menu display/setting unit short description code range Actual and required output frequency FOUT 0.00 - 125.0 actual output frequency FSET 0.00 - 125.0 required output frequency (reference value) Analogue control signal to output frequency reference FSET conversion parameters (Output frequency limit values for remote control) 0.0 - 125.0 req.frequency for 0% analogue signal...
- Page 7 8. Detailed description of displayable values and adjustable drive parameters 8.1. Actual and required output frequency FOUT actual output frequency value - display / setting range : 0.00 - 125.0 Hz When the drive runs the actual output frequency FOUT follows the value of frequency reference FSET considerating acceleration/deceleration limits ACC/DEC.
- Page 8 The parameters F0 and F100 determine the linear conversion from input analogue control signal to output frequency reference and consequently the limit values of output frequency when the remote control mode is selected. F0 < F100 - standard rising linear conversion characteristic, where higher input signal determines higher output frequency, F0 determines minimum and F100 maximum output frequency in the remote control mode F0 >...
- Page 9 8.5. V/f characteristic FBAS - base frequency - setting range : 25.0 - 241.0 Hz Parameter FBAS determines the maximum voltage reaching frequency, and consequently the constant ratio V/f, flux, and available torque for frequencies under FBAS, if a compensated linear V/f characteristic is set. For frequencies above FBAS, the output voltage remains constant (available maximum voltage), and consequently the magnetic flux and available motor torque decrease („field weakening“).
- Page 10 When the constant available motor torque at reduced speed is required, the linear V/f curve should be used with increased voltage at low frequencies (under 1/2 FBAS) to compensate the voltage drop in motor windings. Voltage level at very low frequencies should be set as a compromise of the required torque and the danger of overheating the motor due to decreased efficiency of the motor selfcooling.
- Page 11 UE-0, UE-1, UE-2, UE-3 - external user sets of parameters (located in the EEPROM inside the FRECON MINITERMINAL control pod, so they enable to transfer sets of parameters from one inverter to another one) FA-0, FA-1, FA-2, FA-3 - factory sets of parameters (located in ROM, not reprogrammable by user), they contain the most frequently used settings of parameters to help a user with tuning the drive for common use.
- Page 12 The active set is located in the working (active) memory RAM inside the inverter. The active set has no identification and contains all active functional parameters. The values of active parameters can be displayed and adjusted using the FRECON MINITERMINAL control pod. All active parameters changes can be realised even during motor running with immediate response in function.

UI-0 of two other destination inverters is described in the following steps : connect the control pod FRECON MINITERMINAL to the source inverter load (READ) the user set UI-0 into the working area (active set) - Page 14 11. Failures signalization When an operational failure or a parameter set manipulation error occures, the corresponding error code is signalized on the display as a flashing message „Er.NN“, where NN is the numeric error identifier. 11.1. Operational failures Er.00 - internal protection inverter shut-down cause: short circuit, overcurrent, Ixt, overvoltage, undervoltage, damaged motor, motor or power supply connection failure, motor windings connection failure...
- Page 15 Er.19 - checksum error of the loaded parameter set WARNING! New data from the selected parameter set were loaded into the working area, however they shouldn’t be used as they could contain incorrect data. solution: Quit the signalization and repeat the READ operation. If the failure occures again, read another parameter set.
