No. Signal Default Description Parameter

R1 Relay N.O. Fault Normally open contact for output relay. A055

R2 Relay Common – Common for output relay.

R3 Relay N.C. Fault Normally closed contact for output relay. A055

Analog Output Select DIP

Switch

0-10 V

Sets analog output to either voltage or current. Setting must match Analog

Out Sel (A065).

Sink/Source DIP Switch Source (SRC) Inputs can be wired as Sink (SNK) or Source (SRC) via DIP Switch setting.

01 Stop

Coast

The factory-installed jumper or a normally closed input

must be present for the drive to start.

02 Start/Run FWD Not Active

Command comes from the integral keypad by default. To

disable reverse operation, see Reverse Disable (A095).

04 Digital Common –

For digital inputs. Electronically isolated with digital

inputs from analog I/O and opto outputs.

05 Digital Input 1 Preset Freq Program with Digital In1 Sel (A051). A051

06 Digital Input 2 Preset Freq Program with Digital In2 Sel (A052). A052

08 Digital Input 4 Jog Forward Program with Digital In4 Sel (A054). A054

09 Opto Common -

For opto-coupled outputs. Electronically isolated with

opto outputs from analog I/O and digital inputs.

11 +24V DC –

Referenced to Digital Common.Drive supplied power for

digital inputs. Maximum output current is 100 mA.

12 +10V DC –

Referenced to Analog Common. Drive supplied power

for digital 0-10 V external potentiometer. Maximum

output current is 15 mA.

P038

13 +/-10V In

Not Active

For external 0-10 V (unipolar) or +/-10 V (bipolar) input

supply (input impedance = 100 k Ohm) or potentiometer

wiper.

A123, A132

14 Analog Common –

For 0-10 V In or 4-20 mA In. Electronically isolated with

analog inputs and outputs from digital I/O and opto

outputs.

15 4-20mA In

Not Active

For external 4-20 mA input supply

(input impedance = 250 Ohm).

P038, A051-A054,

A132

16 Analog Output OutFreq 1-10

The default analog output is 0-10 V. To convert to a

current value, change the Analog Output Select DIP

Switch to 0-20 mA. Program with Analog Out Sel (A065).

Max analog value can be scaled with Analog Out High

(A066).

Maximum Load: 4-20 mA = 525 ohm (10.5 V)

0-10 V = 1k ohm (10 mA)

19 RS485 Shield -

Terminal should be connected to safety ground- PE

when using the RS485 communications port.

Important: I/O Terminal 01 is always a coast-to-

stop input except when Start Source (P036) is set

to “3-Wire Control.” In three-wire control, I/O

Terminal 01 is controlled by Stop Mode (P037). All

other stop sources are controlled by Stop Mode

(P037).

2-Wire Per P037 Coast

RS485 Port Per P037 Coast

Important: The drive is shipped with a jumper installed between I/O Terminals 01 and 11. Remove this

jumper when using I/O Terminal 01 as a stop or enable input.

Two-wire control shown. For three-wire control, use a momentary input on I/O Terminal 02 to

command a start. Use a maintained input for I/O Terminal 03 to change direction.

When using an opto output with an inductive load such as a relay, install recovery diode parallel to the

relay as shown to prevent damage to the output.

When the ENBL enable jumper is removed, I/O Terminal 01 will always act as a hardware enable, causing

a coast to stop without software interpretation.

0-10 V In and 4-20 mA In are distinct input channels and may be connected simultaneously. Inputs may

be used independently for speed control or jointly when operating in PID mode.
