EPL Drive Information Parameters and I/O Flags
Table 75 gives all the user-set control parameters for EPLD0. For higher
numbered ETHERNET Powerlink drives (EPLD), work from EPLD0 and add
n x 16 to each parameter number. For example, for EPLD1 Node ID, add 1 x
16
to the parameter number for EPLD0 Node ID (P37632) to get P37648.
The control parameters must be set by the user before the network is started.
Save the parameters denoted with an asterisk (*) with the
ESAVE command.
Control Parameters for EPLD0 P Number
Node ID * P37632
Reserved P37633
Drive mode * P37634
TCP/IP Port number * P37635
* Saved with the ESAVE command
Table 75 Control Parameters for EPLD0
The “Drive Mode” parameter is derived from the DSP-402 specification, and
takes a value of 7 for Interpolated Position Mode, the only supported mode. It
is included as a parameter to accommodate a possible future expansion in
supported modes. The TCP/IP Port number (P37635) is required for TCP/IP
connection to a drive, discussed in the section “Basic Ethernet Connections”
on page 179.
Table 76 gives all the status parameters for EPLD0. The controller
automatically updates the status parameters, and the user should not modify
them.
Status Parameters for EPLD0 P Number
OS download or reset progress or status P37636
EPL Operation Error Code (0 means no error) P37637
Attached Axis Number (Established by the ATTACH AXIS
command)
P37638
Node Status (0=never found, 1=found, 2=found then lost) P37639
Operational Duration in Seconds P37640
Node Failure Count P37641
Reserved P37642-P37647
Table 76 Status Parameters for EPLD0
P37636 indicates the current progress, or final status of an OS download or
reset initiated by ACR-View. The potential values and their meanings are
listed in Table 77 in the order that would occur during the process. The status
values persist after the operation is complete.
