power up of the controller. If this value is set and saved in non-volatile memory, it will be restored
upon reset until a master reset is given to the controller.
The default format describes the format for numerical values, which are returned when the command is
interrogated. The format value represents the number of digits before and after the decimal point.
Controller Usage
The controller usage indicates which models within the DMC-1400 Econo Series line support the
current command. Controllers referenced in this manual are the DMC-1410, DMC-1411, DMC-1412,
DMC-1414, DMC-1415, DMC-1416, DMC-1417 and DMC-1425. ALL indicates that all Econo
controllers support the specific command.
Servo Update Rates
The standard servo update period on all E-Series Motion Controllers is 1msec. To change the servo
update, use the command, TM. The controller firmware will allow operation down to 250 usec per
sample.
Fast Firmware (DMC-1415/1416/1425)
The DMC-1415, DMC-1416 and DMC-1425 motion controllers can operate in ‘fast mode’ that allows
operation down to 125 usec per sample.
In order to run the motion controller in fast mode, the fast firmware must be uploaded. This can be
done through the Galil terminal software such as DMCTERM and WSDK. Use the menu option,
"Update Flash EEPROM" to change the controller firmware. The fast firmware is included with the
controller utilities.
When operating in fast mode, there are functions that are disabled and/or altered.
