PID control, single motor
Input signals Output signals
• Setpoint selected from: control panel setpoint/constant
setpoint /analog input (AI1)
• Analog output AO1: Output frequency
• PID feedback (AI2) • Analog output AO2: Motor current
• Start/stop selection (DI1) • Relay output 1: Damper control
• Constant speed/frequency selection (DI3) • Relay output 2: Running
• Start interlock 1 (DI4) • Relay output 3: Fault (-1)
1) Connected with jumpers at the factory.
2) Only frames R6…R9 have terminals 40 and 41 for external 24 V AC/DC input.
