AG[N] - Analog Gains Array

Purpose:
Sets the gains for preconditioning analog signals, when RM = 1:
ƒ

AG[1] sets the gain of analog input #1 when used as a torque command (UM=1, 3).

ƒ

AG[2] sets the gain of analog input #1 when used as a speed command (UM=2).

When RM = 0, the AG[N] parameters are ignored.

The meaning of the analog gains depends on the unit mode, as shown in the following
table.

Value Description

Units

UM=1, 3

One volt at the analog reference input
command controls the motor phase current
of AG[1] amperes.

Ampere/volt

UM=2

One volt at the analog reference input
command controls a speed of AG[2]
counts/second.

Count/second/volt

Table 3-2: Analog Gains - Analog Input #1

Notes:

ƒ

AG[1]defines motor phase amperes and not RMS amperes.

ƒ

In stepper mode (UM=3), the two external inputs play different roles: The analog
input voltage sets the motor power while the follow pulse/direction or quadrature
input determines the position.

ƒ

The polarity of the analog reference signal may be reversed by setting the sign of
the AG[N] parameter accordingly.
