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)

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).

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.
