PowerFlex 4 and 40 AC Drives
PowerFlex 40
• The control logic is 24V DC and can be set for either
Sink or Source control via a DIP switch setting.
• Control terminal screws are sized for a conventional
blade screw driver.
• I/O Terminals 1, 2 and 3 are dedicated for Stop, Start and
Reverse operation respectively. These I/O Terminals can
be programmed for 2- or 3-Wire operation to meet
application requirements.
• I/O Terminals 5, 6, 7 and 8 are programmable and
provide added flexibility. Programmable functions
include Local Control, Jog, Second Accel/Decel, Clear
Fault, Preset Frequencies, RS485 Control and Auxiliary
Fault.
• Speed can be controlled via a 0…10V input and/or 4…20
mA input. Both inputs are independently isolated from
the rest of the drive and can be used for applications such
as PID. Voltage input can be programmed for bipolar
operation.
• The drive is shipped with a jumper installed between I/O
Terminals 01 and 11 to allow out of box operation from
the keypad.
