2.4.4 Connection of the power regeneration common converter (FR-CV)
When connecting the power regeneration common converter (FR-CV), connect the drive unit terminals (P/+ and N/-) and
power regeneration common converter (FR-CV) terminals as shown below so that their symbols match with each other.
∗1 Keep input terminals (R/L1, S/L2, T/L3) open. Incorrect connection will damage the drive unit.
∗2 Do not insert an MCCB between the terminals P/+ and N/- (between P/L+ and P/+, between N/L- and N/-). Opposite polarity of terminals
N/- and P/+ will damage the drive unit.
∗3 Always connect the power supply and terminals R/L11, S/L21, T/MC1.
Operating the drive unit without connecting them will damage the power regeneration common converter.
∗4 Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10, RES signal. (Refer to page 100)
∗5 Be sure to connect terminal RDYB of the FR-CV to the X10 signal or MRS signal assigned terminal of the drive unit, and connect terminal
SE of the FR-CV to terminal SD of the drive unit. Without proper connecting, FR-CV will be damaged.
NOTE
The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1, S2/L2, T2/L3 must be matched.
Use sink logic (factory setting) when the FR-CV is connected. The FR-CV cannot be connected when source logic is
selected.
Do not remove the jumper across terminals P/+ and P1.
