Control Wiring
All control wiring connects directly to the control terminal board on the drive. The
following pictures show typical control wiring connections that are available on FRENIC-
HVAC drives.
Description of Control Connections
•
Analog speed reference input:
o VFD terminals 11 & 12 for 0-10VDC OR
o VFD terminals 11 & C1 for 0/4-20mA
Used for remote control of drive speed
o
•
Analog monitor output:
o VFD terminals 11 & FM1 for 0-10VDC
o Drive function code F31 sets signal function, default is output frequency
o For 0-10VDC output, set drive SW4 to VO and function code F29 to 0
o For 4-20mA output, set drive SW4 to IO and function code F29 to 1
o For 0-20mA output, set drive SW4 to IO and function code F29 to 2
o VFD terminal 11 & FM2 for 0/4-20mA
o Drive function code F35 sets signal function, default is output frequency
o For 0-10VDC output, set drive SW6 to VO and function code F32 to 0
o For 4-20mA output, set drive SW6 to IO and function code F32 to 1
o For 0-20mA output, set drive SW6 to IO and function code F32 to 2
