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 >>

Digital input and maximum frequency

1. Pr.1 and 18 limit the output to 120 Hz. Use Pr.18 to change the maximum frequency. 2. If you want to output the binary input as is, setting Pr.304 = 1 (Bi... More Details >>
