Result: log1_ Ana Offset =819
The following changes are required on the basis of Example 7-3.
Table 7-14 Parameter settings in Example 7-5
d3.24 Analog1_Offset Sets offset data for
external analog signal 1
Set to 819
d3.29 Analog_Speed_Factor Sets the proportion
between analog signals
and output speed
Set to 4447
d3.00 Store_Loop_Data 1: Storing all configured
parameters for the
control loop
10: Initializing all
parameters for the
control loop
Set to 1
Example 7-6: Analog
– speed mode (setting the dead zone voltage and
offset voltage)
Requirement: Set the offset voltage to 1V, the dead zone voltage to 0.5V to 1.5V, and the max speed
corresponding to 10V to 3000 rpm. Select analog channel 1 (AIN1) to control the speed.
