Product Description:
The RF2G21A0A00 is a versatile RF2 servo amplifier, featuring a robust position control mode. As an RF2 servo amplifier, the RF2G21A0A00 uses a MOS-FET control system, which can come in either of the following forms: PWM control and sine wave drive. In PWM control, a series of pulses drives the motor. Depending on the width of the pulses in PWM mode, the motor speed, position, and torque can be controlled. On the other hand, in sine wave drive mode, a sinusoidal wave with varying amplitudes or frequencies may be used to fine-tune the motor parameters during operation.
The RF2G21A0A00, specifically, requires a DC main power supply of 48 V. At most, the drive can tolerate a deviation of 10 percent, corresponding to an input DC supply range of 43.2 V to 52.8 V. The RF2G21A0A00’s control power supply is different from the main circuit supply. The control circuit for this servo amplifier only requires a nominal voltage of 5 V. Similar to the main circuit power supply, the drive’s control circuit can tolerate some deviation. The difference, however, is that the control power supply can only tolerate a maximum of 5% deviation from the nominal input. Considering this deviation, the RF2G21A0A00’s control circuit can function within a voltage range of 4.75 to 5.25 VDC.
The RF2G21A0A00 has external dimensions of 116 mm x 30 mm x 70 mm. With its efficient construction, the RF2G21A0A00 only weighs around 230 grams. During operation, this servo drive can withstand a maximum vibration of 4.9 m/s^2 at a frequency range of 10 to 55 hertz along any axis. The maximum impact that the RF2G21A0A00 can tolerate during operation is around 19.6 m/s^2.
