2.1 VELOCITY CONTROL MODE
2.1.1 Start-up Procedure
A. Check that the serial spindle starts up normally and is ready for
operation.
B. Prepare and check the PMC ladder.
C. Set the detector-related parameters according to the system
configuration.
D. Set the parameters related to spindle speed specification.
E. Check that the spindle rotates at the desired speed.
G. Make a velocity loop gain adjustment as required.
• No.4040, 4041 : Velocity proportional gain
• No.4048, 4049 : Velocity integral gain
F. Execute an acceleration/deceleration function and adjust the
acceleration/deceleration constant.
• No.4069 to 4072 : Acceleration/deceleration constant
2.1.2 Overview
The velocity control mode is a function for exercising velocity control
to rotate the spindle motor according to a velocity command from the
CNC.
NOTE
On a CNC screen (such as the spindle monitor
screen and the adjustment screen), the velocity
control mode is indicated as "NORMAL
OPERATION MODE".
2.1.3 System Configuration
The velocity control mode is applicable to all detector configurations.
For system configurations, see Subsection 1.3.3, "Typical Detector
Configurations".
