G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
z
Speed Command Status Output (VCMD)
• This output turns ON when the speed command is in the Speed Control Mode.
• The output is always OFF except in the Speed Control Mode.
• With the default settings, the output is not allocated.
z
Remote Outputs (R-OUT1 and R-OUT2)
• Remote Output 1 (R-OUT1) turns ON and OFF according to the ON/OFF status of bit 16 in the
Digital outputs (60FE hex).
• Remote Output 2 (R-OUT2) turns ON and OFF according to the ON/OFF status of bit 17 in the
Digital outputs (60FE hex).
• With the default settings, the outputs are not allocated.
z
Magnetic Pole Position Estimation Completion Output (CS-CMP)
• This output turns ON when the magnetic pole position estimation is completed.
• With the default settings, the output is not allocated.
These are the specifications of the external encoder that can be used in conjunction with the Servo
Drive.
*1 Set the number of pulses per magnetic pole pitch (or one cycle of electrical angle) to at least 2,048 pulses.
*2 OMRON checked the connection of these products in serial communications by using each representative
model. Although the connection is confirmed, it does not mean that the functions and performance are
guaranteed in the resolution, model, and all aspects of an external encoder.
*3 This represents the encoder speed supported on the Servo Drive. Check separately the external encoder
operation manual for its supported speed.
*4 For the external encoder signal cable, use a shielded twisted-pair cable with 0.18 mm
2
or thicker core wires.
*5 We recommend you to use a 5 V power supply with the double wiring technique to reduce the effects of a
voltage drop if the wiring length is long.
