Standard Features

• Short Circuit Protection: Protects control from short circuits.
• Electronic Motor Burnout Protection: Shuts down the control if a prolonged overload condition exists.
• Active Bridge: Limits AC Line inrush current.
• Power Transistor Short Circuit Protection: Prevents high speed runaway if the power transistor shorts.
• Heat Spreader: Prevents power transistor failure during momentary overload conditions.
• LEDs: Power on (ON), Stop (STOP) and Overload (OL).
• Auto AC Line Select: Control automatically adjusts for 115 VAC or 230 VAC – 50/60 Hz.
• Start/Stop Switch: Provides electronic start/stop function.
• Output Run Relay: Indicates state of control – (Run or Stop)

Jumper Selectable Features

• J1 (T/90V/180V) selects nominal motor voltage or tachometer generator feedback.
• J2 (1.7A, 2.5A, 3.5A, 5.0A, 7.5A, also low current range) selects motor current. See general performance specifications.
• J3 (TCL/NTCL) selects timed or non-timed current limit.
• J4 (7V/50V) selects tachometer generator voltage.
• J5 (NC/NO) selects normally closed or open run relay contacts.

Trimpot Adjustments

• Acceleration (ACCEL) • Deceleration (DECEL)
• Maximum Speed (MAX) • Minimum Speed (MIN)
• Current Limit (CL) • Timed Current Limit (TCL)
• IR Compensation (IR) • Jog (JOG)

Optional Features

• On/Off AC line switch (P/N 9341): Disconnects the AC line.
• FWD-BRK-REV switch (P/N 9339): Provides reversing and dynamic braking.
• Run-Stop-Jog switch (P/N 9340): Selects speed setting from either main potentiometer or JOG trimpot.
• Signal Isolator KBSI-240D (P/N 9431): Provides isolation between non-isolated signal sources and the KBPW-240D.
• Anti-Plug Reversing Module APRM (P/N 9378A): Provides electronic braking and instant reversing.
• Auto/Manual Switch (P/N 9377): Selects either isolated signal (from KBSI-240D) or main speed potentiometer signal.

*Note: Requires CE RFI filter KBRF-200A (KB P/N 9945) or equivalent.
