Magnetic contactor S-T21 S-T21 S-T21 S-T25 S-T35 S-T50 S-T65 Notes: 1. This is a time for the protective function of FR-CV-(H) to activate. Refer to relevant Servo Amplifier Instruction Manual for the time for the protective function of the servo amplifier to activate. 2. The mentioned value is a power supply capacity for FR-CV-(H). The actually required capacity depends on the sum of the power supply capacities for the servo amplifiers connected.

* Cautions when selecting the power regeneration common converter Capacity [kW] of FR-CV-(H) ≥ Total rated capacity [kW] of servo amplifiers connected to FR-CV-(H) × 2

Note that when Capacity [kW] of FR-CV-H ≤ Total rated capacity [kW] of servo amplifiers connected to FR-CV-H × 2.5, the maximum torque of the servo motors connected must be 200% or lower. When Capacity [kW] of FR-CV-H > Total rated capacity [kW] of servo amplifiers connected to FR-CV-H × 2.5, the maximum torque of the servo motors connected is not limited.
