HVAC default direct I/O control
Input Signals Output signals
• Analog frequency/speed reference (AI1) • Analog output AO1: Output frequency
• Start/stop selection (DI1) • Analog output AO2: Motor current
• Constant speed/frequency selection (DI3) • Relay output 1: Damper control
• Start interlock 1 (DI4) • Relay output 2: Running
• Relay output 3: Fault (-1)
Notes:
1) Ground the outer shield of the cable 360 degrees under the grounding clamp on the grounding shelf for
the control cables.
2) Connected with jumpers at the factory.
3) Only frames R6…R11 have terminals 40 and 41 for external 24 V AC/DC input.
