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

04 Digital Common –
For digital inputs. Electronically isolated with digital inputs
from analog I/O.

11 +24V DC –
Drive supplied power for digital inputs.
Maximum output current is 100mA.
12 +10V DC –
Drive supplied power for 0-10V external potentiometer.
Maximum output current is 15mA.

Not Active
For external 0-10V input supply
(input impedance = 100k ohm) or potentiometer wiper.
P038
14 Analog Common –
For 0-10V In or 4-20mA In. Electronically isolated with
analog inputs from digital I/O.
15 4-20mA In Not Active
For external 4-20mA input supply
(input impedance = 250 ohm).
P038
16 RS485 (DSI) Shield –
Terminal should be connected to safety ground - PE
when using the RS485 (DSI) communications port.
(3)
Only one analog frequency source may be connected at a time. If more than one reference is connected at the same
time, an undetermined frequency reference will result.

Important: I/O Terminal 01 is
always a coast to stop input except
when P036 [Start Source] is set to
“3-Wire” control. In three wire
control, I/O Terminal 01 is controlled
by P037 [Stop Mode]. All other stop
sources are controlled by P037
[Stop Mode].
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 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.
