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.

The factory-installed jumper or a normally closed input
must be present for the drive to start.

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,

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.
1 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.
2 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.
3 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.
4 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.
5 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.
