Control circuit power supply

If the MC on the input side is shut off using the fault output of the FR-E500, the inverter's fault records are left in the faults history. More Details >>

Inverter installation interchange attachment

Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K. More Details >>

Parameter unit display

Setting Pr.37 to the machine speed at 60 Hz switches the frequency monitor to the rotations per minute monitor.Note that the speed setting must be input in a... More Details >>

Operation command terminal switching

It rotates in the forward direction while STF is ON.And then, when STR is turned ON and STF is turned OFF, the inverter decelerates down to 0 Hz within the s... More Details >>

Vector inverter option

Just by adding this option, encoder pulses connected to the inverter or option are output.You can also divide the pulse train output. 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 >>

Driving two motors with different capacities

It is OK to drive motors by switching the electromagnetic contactor on the inverter's output side.It is also OK if the motor capacity is small. However, if t... More Details >>

Availability of parameter unit

You cannot use the FR-PU04 with the FR-HC. More Details >>
