Because INVT MVD support voltage (0-10V) and current (0-20mA) two type analog sources. Those two analog sources share one circuit, that is 0V=0mA and 10V=20mA, so INVT MVD current analog range is 0-20mA.
The maximum distance between the motor and the MVD cable 2km without ouput reactor;
If MVD with output reactor or sine-wave filter can support maximum 5km.
Firstly calculate the MVD poss loss;
Secondly 1HP can cooling 2.5kw power. 1HP=12000btu; 1btu=0.252kcal;
Finally can calculate the air conditioning power. Above data is rough design of reference data, the actual data please contact with INVT technical support engineer.
Yes.INVT MVD can support motor temperature sensor terminals.
One solution is use temperature controller to collect signal, the information is showing on controller;
The other solution is use INVT PLC+PT to collect signal, the information is showing on HMI.
INVT MVD can drive synchronous motor and asynchronous motor , only the MVD model name is different, others include cabinets,components and software is the same. Customer can set parameters to drive different motors.
Yes.INVT MVD has this function. When the grid line power off briefly 0.1s-5s,the MVD can continue drive motor without fault.
Because when MVD drive motor running at 25-35Hz,the speed of the motor and load reach at resonance frequency point,so the MVD output current vibration is huge. At this time, we can setting jumping frequency to aviod this resonance frequency point.
Yes.INVT MVD can drive slip-ring motor.
But need change the slip-ring motor rotor connection and remove brush.
Right diagram is reference for slip-ring motor renovation.
The INVT MVD don't need input and output filter.
Because INVT MVD use shiffting transformer and multi-level output principle,it can counteract below 50th odd harmonic so the VFD input and output harmnic is low(THD less than 4%), input power factor is high (>0.97)and output du/dt is low,so it don't need input and output filter.
