AX1500 Motor Controller User’s Manual 141
Reading & Changing Operating Parameters at Runtime
^1C - Joystick Max 2 MS
^1D - Joystick Max 2 LS
Effective: Instantly
These parameters are the Gains values that are loaded after the controller is reset or pow-
ered on. These Gains apply to both channels. Gains can be changed at Runtime, and values
can be different for each channel using separate commands (see page 142).
Gains values are integer number from 0 to 63. This number is divided by 8 internal so that
each increment equals 0.125.
Reading & Changing Operating Parameters at Runtime
It is possible to change several of the controller’s operating modes, on-the-fly during nor-
mal operation. Unlike the Configuration Parameters that are stored in Flash (see above),
the Operating Parameters are stored in RAM and can be changed indefinitely. After reset,
the Operating Parameters are loaded with the values stored in the Configuration Parameter
flash. They are then changed using RS232 commands.
Use the command following commands to Read/Change the Operating Modes
Syntax: ^mm Read Parameters at location mm
^mm DD Write Parameters DD in location DD
mm and DD are Hexadecimal values.
The table below lists the available parameters
