PowerFlex 4 and 40 AC Drives
Control Wiring
PowerFlex 4
• 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 4 and 5 are programmable and provide
added flexibility. Programmable functions include:
– Local Control
– Preset Frequencies
– Jog
– RS485 Control
– Second Accel/Decel
– Auxiliary Fault
– Clear Fault
• Speed can be controlled via a 0…10V input or 4…20
mA input. Both are electrically isolated from the drive.
• One form C relay can be programmed to provide the
status of a wide variety of drive conditions.
• The drive is shipped with a jumper installed between
I/O Terminals 01 and 11 to allow out of box operation
from the keypad.
