Analog Control
and Operation
and Operation
This section describes how the motors may be operated using analog voltage commands.
Mode Description
The AX2500/2850 can be configured to use a 0 to 5V analog voltage, typically produced
using a potentiometer, to control each of its two motor channels. The voltage is converted
into a digital value of -127 at 0V, 0 at 2.5V and +127 at 5V. This value, in turn, becomes the
command input used by the controller. This command input is subject to deadband thresh-
old and exponentiation adjustment. Analog commands can be used to control motors sep-
arately (one analog input command for each motor) or in mixed mode.

Important Notice
The analog mode can only be used in the Closed Loop speed or position modes
when Optical Encoders are used for feedback. Position potentiometers or tachome-
ters cannot be used since there is only one analog input per channel and that this
input will be connected to the command potentiometer.
