4. Verify that the Sink (SNK)/Source (SRC) jumper is set to match your
control wiring scheme. See the Control I/O Wiring Block Diagram
on
page 32 for location.
5. Verify that the Stop input is present or the drive will not start.
Applying Power to the Drive
6. Apply AC power and control voltages to the drive.
Start, Stop, Direction and Speed Control
Factory default parameter values allow the drive to be controlled from the
keypad. No programming is required to start, stop, change direction and control
speed directly from the keypad.
If a fault appears on power up, see Fault Descriptions
on page 135 for an
explanation of the fault code.
Variable Torque Fan/Pump Applications
For improved motor tuning performance when using a premium efficient motor
on a variable torque loading SVC mode, set A530 [Boost Select] to 2 “35.0, VT”.
The default control scheme is Source (SRC). The Stop terminal is jumpered to
allow starting from the keypad or comms. If the control scheme is changed to
Sink (SNK), the jumper must be removed from I/O Terminals 01 and 11 and
installed between I/O Terminals 01 and 04.
If I/O Terminal 01 is used as a stop input, the jumper between I/O Terminals 01
and 11 must be removed.
To disable reverse operation, see A544 [Reverse Disable].
