AG[N] - Analog Gains Array
Purpose:
Sets the gains for preconditioning analog signals, when RM = 1:
AG[1] sets the gain of analog input #1 when used as a torque command (UM=1, 3).
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:
AG[1] defines motor phase amperes and not RMS amperes.
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.
The polarity of the analog reference signal may be reversed by setting the sign of
the AG[N] parameter accordingly.
