Switching between forward and reverse rotations

When you switch the inverter to the reverse rotation while it is rotating in the forward direction, it decelerates to stop over the deceleration time (set wi... More Details >>

Installation clearance of inverters

Keep 1 cm or more of clearance for 3.7 K or smaller, and 5 cm or more for 5.5 K or larger.If the clearance is too small, the cooling effect is lowered. Secur... More Details >>

Surge voltage of 400 V inverter

1. Since the voltage resistance of the standard motor is not improved, it is recommended to use an "insulation-enhanced motor".If you are using an insulation... More Details >>

Selection of high-duty brake resistor
