Control Modes
Your AMP-204C / AMP-208C VAO module now supports three
control modes:
a. Mode1: PWM mode
This control mode adjust PWM duty cycle according to fixed PWM
frequency and variable speeds as shown in figure below. The fixed
PWM frequency is1/T and the PWM duty cycle W
1
/T, W

with
different PWM pulse width at W

. See below for
details on VAO table. To use this control mode to set
1. Set up control mode: Use APS_set_vao_param ( ) to set
up
value of VAO_TABLE_OUTPUT_TYPE
parameter to 0x1
.
2. Set up fixed PWM output frequency: Use
APS_set_vao_param( ) to set up parameter
VAO_TABLE_PWM_Config
in unit of Hz. Valid frequency
input range now is 3Hz ~ 50MHz.
