A momentary input will
start the drive. A stop
input to I/O Terminal 01
will stop the drive as
specified by P045
[Stop
Mode]. I/O Terminal 03
determines direction.

Opto Output (1 & 2)
(1)
t069 [Opto Out1 Sel]
determines Opto-
Output 1 (I/O Terminal
17) operation.
t072 [Opto Out2 Sel]
determines Opto-
Output 2 (I/O Terminal
18) operation.
When using Opto-Output
with an inductive load
such as a relay, install a
recovery diode parallel
to the relay as shown, to
prevent damage to the
output.
Opto-Output 1
Each Opto-Output is rated 30V DC 50 mA (Non-inductive).
Analog Output
(2)
t088 [Analog Out Sel]
determines analog
output type and drive
conditions.

The Analog Output Select jumper must be set to match the analog output signal mode set
in t088
[Analog Out Sel].
(1) Feature is specific to PowerFlex 525 drives only.
(2) Feature is not applicable to PowerFlex 523 series A drives.
