Mitsubishi Electronics FR-S500 Connection of the power regeneration common converter FR-CV

Connection to the Stand-Alone Option

1.6.3Connection of the power regeneration common converter (FR-CV)

When connecting the FR-CV type power regeneration common converter, connect the inverter terminals (P, N) and FR-CV type power regeneration common converter terminals as shown below so that their signals match with each other.

CAUTION

1.Use sink logic (factory setting) when the FR-CV is connected. The FR-CV cannot be connected when source logic is selected.

2.The power input terminals R, S, T must be open. Incorrect connection will damage the inverter. Opposite polarity of terminals N, P will damage the inverter.

3.The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1, S2/L2, T2/L3 must be matched before connection.

4.Use Pr. 60 to Pr. 63 (input terminal function selection) to assign the terminals used for the RES and MRS signals.

5.Do not insert NFB between terminals P-N (P/L+ - P, N/L− - N)

6.Make sure to connect the terminal R/L11, S/L21, T/MC1 to the power supply. Running the inverter without connecting the terminals will damage the power regeneration common converter.

7.The N terminal is not provided for the FR-S520E-0.1K to 0.75K.
