5.1 Programming for Controlling Inverter Speed with 5 Step Analog Output Voltage
1) System Configuration
slot 1
2) Initial Settings
(1) Enabled channel : channel 0
3) Descriptions of the Program
(1) %I0.0.0 turning On leads to write digital value to D/A conversion module.
(2) %I0.0.1 turning On leads to output of "2000"(0 V) on channel 0.
(3) %I0.0.2 turning On leads to output of "2500"(2.5 V) on channel 0
(4) %I0.0.3 turning On leads to output of "3000"(5 V) on channel 0.
(5) %I0.0.4 turning On leads to output of "3500"(7.5 V) on channel 0.
(6) %I0.0.5 turning On leads to output of "4000"(10 V) on channel 0.
