External Encoder Specifications - Omron R88D-KN series User Manual

3 Specifications
 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 output is not allocated.
 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.

3-1-10 External Encoder Specifications

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 2048 pulses.
*2 This represents the encoder speed supported on the Servo Drive. Check separately the external encoder
operation manual for its supported speed.
*3 For the external encoder signal cable, use a shielded twisted-pair cable with 0.18 mm
*4 We recommend you to use a 5 V power supply with the double wiring technique to reduce the effects of a volt-
age drop if the wiring length is long.
