High-frequency input (65 kHz)
24 V incremental encoder input
AB encoder input (optional)

Automatic motor tuning
Perfect matching of the motor and inverter
Measure the stator resistance (RS)
Better performance of the spindle
In the measurement process without having to exert torque
Check the motor phase missing

At 45 ° C without derating
VLT ® 2800 in the ambient temperature of 45 ° was still able to work properly, without derating, and can be up to 40 ° C
A state of continuous work.

Flexible installation
Horizontal mounting
Vertical installation
True side-by-side installation
Does not occur derating
The same is true of the various modules
A thermostatically controlled fan

Cooling plate technology
Reduce the heat in the cabinet
More intensive installation
Cabinet seal better
Protection capability:
