(b) FR-CV capacity [W] ≥ Total of rated capacities [W] × 2 of servo amplifiers connected to FR-CV
(c) The total of used servo motor rated currents should be equal to or less than the applicable current
[A] of the FR-CV.
(d) Among the servo amplifiers connected to the FR-CV, the rated capacity of the servo amplifier with
the maximum rated capacity should be equal to or less the value of than "Maximum servo amplifier
capacity" in the following table.
The following table lists the restrictions.

(2) 400 V class
FR-CV-H power regeneration common converter can be used for the servo amplifier of 600 W to 22 kW.
The following shows the restrictions on using the FR-CV-H.
(a) Up to six servo amplifiers can be connected to one FR-CV-H.
(b) FR-CV-H capacity [W] ≥ Total of rated capacities [W] × 2 of servo amplifiers connected to FR-CV-H.
(c) When FR-CV-H capacity is less than the total of rated capacities of the connected servo amplifiers ×
2.5, make the maximum torque of the connected servo motors equal to or less than 200 % of the
rated torque. When FR-CV-H capacity exceeds the total of rated capacities of the connected servo
amplifiers × 2.5, the maximum torque of the connected servo amplifiers is not limited.
(d) The total of used servo motor rated currents should be equal to or less than the applicable current
[A] of the FR-CV-H.
(e) Among the servo amplifiers connected to the FR-CV-H, the rated capacity of the servo amplifier with

Note 1. Configure a sequence that will shut off main circuit power in the following.
An alarm occurred at FR-CV or servo amplifier.
EM1
(
Forced stop 1
)
is enabled.
2. For the servo amplifier, confi
g
ure a sequence that will switch the servo-on after the FR-CV is read
y
.
3. Configure a sequence that will make a stop with the emergency stop input of the servo system controller if an alarm occurs in
the FR-CV. When the servo system controller does not have an emergency stop input, use the forced stop input of the servo
amplifier to make a stop as shown in the dia
g
ram.

.
6. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.
