A = number of pulses required for 1 motor revolution; B = distance moved for 1 motor revolution.
Both A and B are set up in the position controller according to the equipment parameters in the
servo system. “PPS” refers to “pulses per second”. The position controller will calculate the
frequency and the number of pulses for the pulse instruction according to equipment parameters
A, B and the speed.
y
The position parameter
There are two ways to indicate position:
1. The number of pulses as the unit: Since the number of pulses required for the servo
motor system to reach the target position are known, the positioning controller sends
out the designated number of pulses according to the value set.
2.
Distance as the unit: According to the parameters set in the servo motor system, the
position controller converts the distance into the equivalent number of pulses and
sends it to the servo.
4.1.1.3 Introduction
The maximum pulse frequency of the MC01 module is 200KPPS, and the pulse output interface
uses the high-speed differential output (Line Driver). The MC01 module contains 8 motion control
modes and 2 types of pulse acceleration curves, trapezoid curve and S curve. One MC01 module is
able to control a 1-axis step or servo drive system. The ELC MPU is able to read/write the data in
the module using FROM/TO instructions. A maximum of 8 MC01 modules may be connected to a
single ELC controller for 8 independent axis of control.
