Parameter
“Startup speed” aims at the startup frequency of stepping & servo driver, and in servo
driver this parameter should be set zero. The startup speed refers to the highest frequency of direct
working startup without acceleration of motor.
Reasonable selection of this parameter will improve the machining efficiency, and avoid the low
speed seg
ment with bad motion feature of motor. “Startup frequency” is generally included in the
motor ex-factory parameters, but after installation, its value will vary especially in loading motion,
thus, it should be set based on the actual measurement of motor power and inertia of machine tool.
Parameter confirmation method: set a lower value at first, and repeatedly make the machine
execute typical motions & multi-axis synchronization motion, gradually increase this value until
reaching the max. startup speed. The actual setting value of this parameter is half of the max.
startup speed, with general setting range “300 ~ 400”.

“Single axis acceleration” is used to describe the acceleration/ deceleration capability of each feed
axis, with unit “mm/s2”, depending on the physical feature of machine, such as the quality of motion
part, torque, cutting load and resistance of the feed motor. The larger the value of the parameter is,
the less time the machine will spend in acceleration/ deceleration during motion process, the higher
the efficiency is. Generally, for servo motor system, it should be within “600 ~ 3500”. Set a smaller
value at first, and then repeatedly execute typical motions for a period of time. If there is no
abnormal situation, gradually increase the value. If abnormal condition occurs, reduce the value,
with “50% ~ 100%” insurance allowance.
