Application Control Connection Examples
Two-wire Start/Stop
In Auto mode, closing the contact to terminal 18 will make the drive run.
In any mode, opening the safety interlock contact to terminal 27 will stop
the drive.
Set Parameter 302 to Start.
Set Parameter 304 to External Fault.
Digital Speed Up/down
Closing the switch to terminal 32 will make the drive accelerate. Closing
the switch to terminal 33 will make the drive decelerate.
Set Parameter 306 to Speed up.
Set Parameter 307 to Speed down.
Set Parameter 305 to Freeze reference.
Potentiometer Reference
A manual potentiometer is used as a input reference for the drive.
Set Parameter 308, Terminal 53, Analog Input Voltage, to Reference.
Set Parameter 309, Terminal 53, Min. Scaling, to 0 V.
Set Parameter 310, Terminal 53, Max. Scaling, to 10 V.
Run Permissive
After receiving a run command,
the drive will apply power to the
damper motor and wait until it
receives "permission" via the
switch that is connected to
terminal 16.
Set Parameter 300 to Run Permissive.
Set Parameter 302 to Start.
Set Parameter 304 to External Fault.
Set Parameter 323 to Start Signal Applied.
Two Feedback Signals
The drive processes two
independent feedback
signals during closed loop
operation. It can respond to
the sum, difference,
average, minimum or
maximum of these signals.
Set Parameter 308 to FEEDBACK.
Set Parameter 311 to FEEDBACK
Set Parameter 417 for the desired operation.
Transmitter Connection
The drive's internal 24
VDC power supply is
used to power an
external 4 to 20 mA
transducer.
Set Parameter 314, Terminal 60, Analog Input Curent, to
correspond to the purpose of the 4 to 20 mA signal.
Set Parameter 315, Terminal 60, Min. Scaling, to 4 mA
Set Parameter 316, Terminal 60, Max. Scaling, to 20 mA.
Because the commons of the +24 VDC power supply and the input
reference follower have separate circuit commons, it is necessary to
connect a jumper between terminals 39 and 55.
