setting axis)
coincides
Sample_Time.
Description:
(1) when the instruction starts execution Enable changes from FALSE to TRUE.
Unit reading speed is controlled axis Pulse / s, the sampling period is Sample_Time
parameter, calculated from the current shaft speed:
Assumptions: display means of the terminal speed n units / s, the read pulses per second
Velocity = 10000 Pulse / s, the number of pulses per motor revolution (moter_PPC) = 10000 Pulse
/ rad, the terminal mechanism Screw_Lead lead of 1000units the reduction gear ratio of 1: 2
then:
n = unit / s
= 500 units / s
Output parameters
Display speed of
the current sample
(unit: Pulse / s)
Program Example
Example: Read the current speed shaft AXIS0;
1. variables, and procedures
NS_CC_ReadPulseVelocity_1
Step 1: Following programming instructions call NS_CC_ReadPulseVelocity_1 module
