FLC Connection of the control In order to prevent a malfunction caused by interference voltage supply on the control inputs, the following directions should be observed: ? Use shielded/drilled cables ? Lay shield on one side of the inverter onto earth potential ? Lay control and power cable separately (about 10...20 cm apart) ?

The actual deceleration time is proportional to the frequency change. 100 Hz –––––– x actual deceleration time = delta f Adjustment range: Resolution: Factory setting: 1。 at switch off of the direction of rotation and upon reaching 0Hz. The braking time is or until the next dire。 the drive should decelerate from 60 Hz to 10 Hz. delta f = 60 Hz 10 Hz = 50 Hz = (100 Hz / 50 Hz) x 5 s = 10 s Scurve time For some applications it is of advantage when the drive starts and stops jerkfree. This is achieved through a straightening of the acceleration and deceleration ramps. The straightening time, also called Scurve time, can be adjusted with . Adjustment range: Resolution: Factory setting: 0,00 (off)...5,00 s 0,01 s 0,00 s (off) In order to drive defined ramps with activated Scurve time, the acceleration and deceleration times ( and ) must be adjusted higher than the Scurve time ().

To keep the breakdown torque nearly constant over the entire speed range, the voltage decrease can be pensated with the boost.

Preset about 10 Hz and adjust the boost, so that about the same rate of utilization is reached as with the rated frequency. When the motor, during continuous operation, drives with low speed and too high voltage it can lead to an overheating of the motor. Rated frequency With the adjusted frequency the inverter reaches a maximal output voltage. The adjustment of the rated motor frequency is typical in this case. Note: Motors can overheat when the rated frequency is UAincorrectly adjusted!
