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.
