Q: Why does the analog servo
fail to work properly with the
CTX-2710
A: High frame rate setting results in the
abnormal performance of analog servo.
For analog servo, please choose low frame
rate (15ms).
( See P.3 for How to Select Frame Rate )
Q: What is the difference
between high frame rate and low
frame rate while using digital
servo?
A: High frame rate setting enables shorter
response time. It is suggested to use high
frame rate for digital servo.
