Control Wiring
• 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 semi-programmable and dedicated for Stop, Start, Reverse, and SW Enable inputs.
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 fully programmable and provide added flexibility. Programmable functions include Local
Control, Second Accel/Decel, Clear Fault, Preset Frequencies, RS485 Control, Auxiliary Fault, and Purge.
• Speed can be controlled via (2) analog inputs. Both inputs can be configured for either voltage or current 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. This jumper can be removed when using
I/O Terminal 01 as a Stop or Enable input.
