Product Description:

The RF1G21AEB00 is a remarkable servo amplifier featuring a standard construction and design. Designed by Sanyo Denki, this servo amplifier from the Sanmotion R series is optimized for rotary servo motors with large capacities. Servo amplifiers are important components in a servo system because they provide the power and protection devices for the servomotor. Amplifiers also serve as the interface for amplifying digital signals issued by an external host device, depending on the monitored motor parameter. For most servo systems, the encoder provides the information needed both by the amplifier and the host device to perform real-time motor control.

The RF1G21AEB00’s CN2 port is the dedicated connector for the encoder signal. The CN2 port for this drive has a PADP-10V-1-S housing. As mentioned earlier, servo amplifiers such as the RF1G21AEB00 are typically connected with host equipment or industrial PCs. For this servo amplifier model, the host equipment can be connected either at CN1A or CN1B. To power this servo drive, the CNA port of the RF1G21AEB00 must be connected to a DC supply input with a nominal voltage of 48 V. As an RF1 servo amplifier, the output circuit of the drive is considered as a source (PNP output).

Like other servo drives from the RF series, the RF1G21AEB00 offers position control mode. Considering its size and construction, the RF1G21AEB00 can only withstand a load inertia moment of up to 10 times the motor’s rated inertia. Although the main circuit power supply of this drive requires 48 VDC, the control power supply of this drive only needs 5 V to function. The main circuit can tolerate a deviation of plus or minus 10 percent, while the control circuit can only tolerate an absolute deviation of 5%.
