Essential notes before use 
A.  Checking Motor ID certainly. 
: Enter the motor ID indicated on the motor name plate to the parameter of “P01-01”.   
For details on the motor ID, refer to Chapter 3 of this manual.   
B.  Checking Power of servo drive. 
: FDA7001        ~ FDA7150      : AC 220V 50/60[Hz] 
: FDA7020-H0 ~ FDA7750-H0 : AC 380V 50/60[Hz] 
: FDA7020-H1 ~ FDA7150-H1 : AC 440V 50/60[Hz] 
C.  Checking Encoder ID certainly. 
   When you set the encoder ID to “Enc-0”, you can change the value of P01-13 (Encoder pulse 
rate). But if you set the encoder ID to “Enc-A ~ Enc-R”, you cannot change the value of P01-13. 
   Never connect the encoder cable to COM port. 
D.  Operate servo system after auto-tuning is off. (P02-17) 
: Always cancel the autotuning during normal operation after gain setting using autotuning. 
E.  Motor handling   
: Avoid impacting to the encoder in connecting coupling to the Motor shaft or operating. 
F.  Recommended specification of Encoder wiring.

G.  Separate GND24 (CN1-24, 25) and GND (CN1-1, 8, 26, 33, 34, 36). 
: If connected in common, it may cause malfunction and damage of servo drive. 
H.  Treatment of the servo motor attached holding brake . 
: The brake built in the servo motor is a normal closed type brake. Which is used only to hold 
and can't be used for braking. Use the holding brake only to hold a stopped servo motor. 
I.  Do  not  supply  AC  at  N,  P  connector  when  connect  the  power  line  to 
Small and Medium capacity servo drive. 
: If main power is DC power, because N connector (-) voltage and P connector (+) voltage, 
  burnout of servo drive when N, P connector is supplied AC power. 
  Choose positively necessary AC and DC power, and use.
