2.1 Overview
The CiA CANopen standard DS402 Drives and Motion
Control Device Profile is supported by both Ethernet
® ®
POWERLINK and EtherCAT .
2.2 Firmware Update
The products are delivered with the most recent firmware
version. See chapter 1.4.2 Firmware Updates for information
on upgrading.
The servo drive firmware can be updated via the fieldbus.
The download of new firmware is only allowed in the
unpowered drive state Switch on disabled. If the servo drive
is in another state, the transfer is refused. While the update
is in progress, the servo drive signals the warning Firmware
update in progress. After finishing, the servo drive signals
the warning Firmware update occurred. Power cycle the
servo drive to resume normal operation.
If the servo drive state machine is switched to another
state than Switch on disabled after the firmware update has
begun (that is, during file transfer or after flashing without
a power-cycle), the servo drive switches to state Fault. This
error indicates that a power-cycle is needed before the
servo drive can resume operation. If, for example, a power
failure occurs during upgrading, the servo drive remains in
a state that allows the update process to resume. The
currently installed version can be read from object 0x4000
(see chapter 7.22.4 Parameters 15-40, 15-41, and 15-43:
Version log (0x4000)).
NOTICE
To change the supported fieldbus, update to the
corresponding firmware. After changing the fieldbus, the
original product code is no longer valid.
