Upgrading Firmware on ConDrivers
This application note describes how to field upgrade using a Windows PC.
Most AllMotion
®
ConDriver products are field upgradable. At the time of publication,
field upgradable products include the following:
EZHR17EN
EZHR23ENHC
EZSV23
EZ4AXIS
EZPZ (all versions)
Prerequisites
The firmware on the product must be version 7.02 or higher. If the version is older, it
must be upgraded at the factory. To determine the firmware version, query the product
using the EZ Commander
™ application. (Refer to steps 1-5 and 13 of the Firmware
Upgrade Procedure below.)
The PC should have latest version of EZ Commander
™ installed. At minimum, version
1.3.62 is required. To download the latest version of
EZ Commander™, go to
and click on “EZStepper Windows Application.” The
same application works for steppers and servos.
You must have the new firmware (the upgrade file) for your product accessible on your
local system, e.g., saved to disk. Firmware files are available by request from
AllMotion
®
on a case-by-case basis. Email your request to
The upgrade file has a .amx extension.
Programming voltage on the product to be upgraded must be enabled. On some
boards, this voltage is already enabled; on others, it may be enabled as described
below.
To determine whether the programming voltage is enabled on your board, you may do
either of the following:
-
Run the Firmware Upgrade Procedure, which begins on page 2. If you receive the
“Unrecognized Response” error message in EZ Commander™, the programming
voltage is not being supplied. If this occurs, examine and modify the board as
described in the following instructions.
Or,
-
Examine the board and ensure that the programming voltage pads are connected
together. Refer to the figure on the next page, which is a close-up of the EZ4AXIS
board.
Locate the two small pads near the microprocessor that are surrounded by a
silkscreened line. In the figure, the two pads are ju
st below the “R108” silkscreen.
If the two pads are not already connected together, connect them. Be sure to
connect only the two pads within the silkscreened boundary.
