FUNCTIONING
The alternating voltage from the power line is rectified by a line diode bridge, then electrolytic capacitors smooth out the
pulsating voltage. The intelligent IGBT end stage, driven with sinusoidal modulated pulses, delivers to the motor a
voltage of variable amplitude and frequency. Up to the nominal speed of the motor the voltage vs. frequency is constant.
At low frequencies the ohmic resistance of the motor winding can be compensated (U boost).
Below the nominal revolution the frequency converter is capable of delivering nominal torque; beyond it the
converter delivers constant power.
The converter can be equipped with an optional braking resistor.

8CAUTION
EQUIPMENT HAZARD
Negligence of this warning could cause total damage to the device.
The device is not waterproof!
Prevent the interior of the appliance from the penetration of water!
Take care that no external object (e.g. small metal part, metal powder) or liquid can get inside the device.
Avoid short circuit or ground fault at the output terminal blocks.
It is forbidden to connect any capacitor to the output. Regarding other filters, please ask the
manufacturer’s opinion.
Avoid using contactor at the output because the frequency converter may stop working due to switch-on
overcurrent.
If for other reasons using a contactor is necessary (e.g. switch-over between motors), the switchover of the
output of the frequency converter during operation must be prevented by latching.
Use the shortest possible earthing conductor and avoid earth loops.
Earthing conductors common with machines of higher power (e.g. welding machine, machine tool) must
not be used.
For wiring the control unit use shielded cable.
Use shielded twisted wires, and connect the shielding to the reference point of the inputs.
Observe proper electrostatic discharge procedures (ESD) when handling the frequency converter.
Failure to comply may result in ESD damage to the drive circuitry.
Do not operate the device with any visible damage on it or if its any part is missing.
Do not modify the circuitry of the frequency converter to avoid damages and expiring of the warranty.
Check all the wiring to ensure that all connections are correct after installing the frequency converter
and connecting other devices.
•Cables and fuses
At connecting the frequency converters use mains fuses and wires with cross-section as given in the table.

•Main and Control Circuit Wiring
•Connecting the power line
At connecting the power line comply with following safety measures:
▪Use only circuit breakers that have been designed specifically for frequency converters.
▪If an input switch is used, it is allowed to be used not more than once in every 30 minutes.
▪Use an AC reactor on the input side of the drive:
•to suppress harmonic current,
•to improve the power factor on the power supply side,
•when using an advancing capacitor switch.
•Connecting the motor
At connecting the motor comply with following safety measures:
▪The output of the frequency converter has to be loaded with a three-phase motor. In case of any other load
consult with the manufacturer!
▪Never connect a power source to the drives output.
▪Never short or ground the output terminals.
▪Do not use phase correction capacitors.
▪If using a contactor between the drive and motor, it should never be operated when the drive is outputting a
voltage. Operating while there is voltage output can cause large peak currents, thus tripping the over current
detection or damage the drive.
▪For connecting the output it is recommended to use shielded cable with earthing at both ends.
▪With an output cable of longer than 30 meters, an output choke coil has to be used. If the cable length
exceeds 200 meters, the output choke coil is not enough, because of the excessive capacitive load. In this
case, a sine filter has to be used. Regarding the output choke coil or the sine filter, please ask the
manufacturer’s opinion.
•Connecting the protective earth
At connecting the earthing of the frequency converter comply with following safety measures:
▪Never share the ground wire with other devices such as welding machines, etc.
▪Always use a ground wire that complies with electrical equipment technical standards. Keep ground wires as
short as possible. Leakage current is caused by the drive. Therefore, if the distance between the ground
electrode and the ground terminal is too long, potential on the ground terminal of the drive will become
unstable.
▪When using more than one frequency converter, do not to loop the ground wire.
▪Use earth cable of same cross-section as that of the phase conductors.
•Connecting the control circuitry
At connecting the control circuitry comply with following safety measures:
▪Separate control circuit wiring from main circuit wiring and other high-power lines.
▪The connections of the SR connectors of the control circuitry (digital output) have to be separated from other
connectors of the control circuitry, unless they are used for control purposes.
▪In order to avoid operation errors use twisted pair or shielded twisted pair cables for connecting the control
circuitry.
▪Be sure to earth the shielding with the largest possible contact area between shielding and earth connection.
▪The shieldings have to be earthed at the frequency converter side of the cables.

•Description of the special functions available at the digital inputs (43 to 46)
Start switch: Continuous start command. If more than one input is programmed for start switch, they are in logical
AND relation. All of them must be true for effecting a start command.
Start push button: Pulse type start command. If more than one input is programmed for start push button, they
are in logical OR relation. If any of them is true start command will be sent out.
Reversing switch: Activating the input results in a reversing command. If more than one input is programmed for
reversing switch, then activating each further input results in reversing the direction of the rotation. Example: with
two digital inputs programmed for reversing switch, activating both inputs results in reversing command, that is, the
original direction will be valid.
Jogging: Usually used for adjusting the machinery, starts the motor with the frequency set in menu 83.FJog.
Active is from stop state only.
External error: Causes the appliance to stop with running out on error message (e.g. motor thermal switch,
emergency off, etc.)
Error acknowledgement: Acceptance of the error messages, removal of the disable state.
Stop closing: With closing contact causes the motor to stop according to the preset stopping mode.
Stop opening: With opening contact causes the motor to stop according to the preset stopping mode.
Free run: Causes the motor to stop with running out. When activated, the frequency converter allows the motor to
stop freely.
DC brake: Causes the motor to stop with DC braking. When activated in stop state, the resulting standing torque
permits achieving hold function.
F fixed: The appliance goes to the frequency preset in menu 84.FFix according to the actual run-up and run-down
value.
Motor potentiometer up: With motor potentiometer reference signal, input for increasing the reference signal.
Motor potentiometer down: With motor potentiometer reference signal, input for decreasing the reference signal.
Control/Regulation: Dynamic changeover of the operation modes.
Analogue input swap: Swaps the analogue inputs with each other.
