the command position is zero. This port can sink or source 20mA current at 24V. The resistance
between Pend+ and Pend- is active at high impedance.
ALM+
O
Fault Signal: An OC output signal which is active when one of the following error protection is
activated: over-voltage, over-current, and position following error. This port can sink or source
20mA current at 24V. The resistance between ALM+ and ALM- is low impedance in normal
operation, and will change to high when the drive goes into error protection. The voltage active
level of this false output signal can be configured by configuration software.

Notes:
(1) Shielding control signal wires is suggested; (2) to avoid/reduce interference, don’t tie control signal cables
and power wires together.
3.1.2 Typical Control and Fault Output Connections
The CS-D808 can accept differential and single-ended control signal inputs (open-collector and PNP output). A
CS-D808 has 3 optically isolated control inputs, PUL, DIR, and ENA. Refer to the following two figures for
connections of open-collector and PNP signals.
