6.2: Manage Amplifier and Motor Data
6.2.1: Memory
To maintain amplifier and motor settings, the amplifier uses volatile RAM memory and non-volatile
flash memory. Data can also be saved to disk for backup and distribution.
Volatile and Flash Memory
Volatile memory holds status data and certain user-entered information data during operation,
whereas flash memory permanently stores the data for loading into volatile memory at +24 Vdc
power-up or reset, as described below.
Volatile Flash
Contents erased when amplifier is reset or powered
off.
Permanent. Contents retained when the amplifier is reset
or powered off.
Initial contents read from flash on +24 Vdc power-up.
Contents then updated in real time to reflect certain
operational conditions and changes entered with CME 2
software. At any time, the user can use CME 2 to restore
certain data from flash into volatile memory.
Modified only by using a Save to Flash tool or by closing
certain screens (Motor/Feedback, Basic Setup, Homing, or
CAN Configuration), whose contents are automatically
saved to flash upon closing of the screen.
How the Amplifier Uses Volatile and Flash Memory
As described below, some data resides in flash only, some in volatile memory only, and some in
both.
Data Resides In Data
Flash only This category includes all data represented on the Motor/Feedback screen, Basic Setup screen,
and CAN Configuration screen. This data is automatically saved to flash as soon as its entry is
confirmed (when the user clicks the appropriate Save to Flash button, or closes the screen).
Flash and Volatile Includes all user-entered data represented on other screens, such as gains, limits, and I/O,
faults, and regen settings. Initial values for this data are factory-set in flash. They are loaded
from flash to volatile memory with each power-up or amplifier reset. This data is saved to flash
only when a user clicks the appropriate Save to Flash button. It is flushed from volatile memory
with each power-down or amplifier reset.
Volatile only Includes operating status data such as actual position, actual current, and amplifier
temperature. Such data is never stored in flash. It is flushed from volatile memory with each
power-down or amplifier reset.
6.2.2: Disk Storage
Amplifier Data Files and Motor Data Files
At any time, the user can save certain data from volatile and flash memory to a file on disk. From
the Main screen, the user can save all user-entered data represented on all screens (the data
described as Flash only and Flash and Volatile on p. 125). This data is saved in a Copley Controls
amplifier data file with a .ccx filename extension.
From the Motor/Feedback screen, the user can save all data represented on the Motor/Feedback
screen. This data is saved in a Copley Controls motor data file with a .ccm filename extension.
A .ccx file can be restored to return the amplifier to a previous state or to copy settings from one
amplifier to another, as described in Quick Copy Setup Procedure (p. 127). This procedure can be
performed via a direct RS-232 serial connection or on node amplifiers via the serial connection
gateway amplifier.
