External wiring for CC-Link operation

For the combination of the FR-A500 + FR-A5NC, Pr.338 and Pr.339 are used to specify whether the external signals or CC-Link commands are used to set the runn... More Details >>

Multi-speed operation

Use the first contact (relay) for the forward (or reverse) rotation between the terminals STF and SD. Use the second contact (relay) for the high-speed comma... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

All parameters returned to initial values

The parameters of the A500 series are stored in the EEPROM.The reason why all parameters returned to the initial values is considered that you may have opera... 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 >>
