This table assumes that Discrete Output Polarity is set to Active High. If Discrete Output Polarity is set to Active
Low, reverse the voltage values.
Important
If you assign Velocity Switch to the discrete output, you should also configure Velocity Switch Setpoint.

Overview
Discrete outputs have two states: ON (active) and OFF (inactive). Two different voltage
levels are used to represent these states. Discrete Output Polarity controls which voltage level
represents which state.
Procedure
Set Discrete Output Polarity as desired.
The default setting is Active High.
