Application macros
PFC macro
This macro provides parameter settings for pump and fan control (PFC) applications.
To enable, set the value of parameter 9902 to 7 (
PFC CONTROL).
Note: Parameter 2108 START INHIBIT must remain in the default setting, 0 (OFF).
Connection example:
Input signals Output signals Jumper setting
• Analog ref. and actual (AI1, 2)
• Start/stop – manual/PFC (DI1, 6)
• Run enable (DI2)
• EXT1/EXT2 selection (DI3)
• Interlock (DI4, 5)
• Analog output AO1: Frequency
• Analog output AO2: Actual 1
• Relay output 1: Running
• Relay output 2: Fault (-1)
• Relay output 3: Aux. motor ON
or
Note: Use the following switch-on order:
1. EXT1/EXT2
2. Run Enable
3. Start.
EXT1/EXT2 selection: Activation selects PFC control
