Parameter Access Error Messages
Whenever there is an invalid parameter access message, the drive will respond with an error message containing the fault code for that
particular error. Parameter access pertains only to16 Word and 6 word messages.
#
16 Word Input/Output Message
If an erroneous Parameter Access message is sent to the drive, the drive will respond with a fault message. The MSB of byte 16 of the fault
response will be set. If the fault is a read parameter data fault, byte 16 of the response message will contain 83h, read parameter function
code 03h with the MSB set. If the fault is a write parameter data fault, byte 16 of the response message will contain 90h, write parameter
function code 10h with the MSB set. Byte 19 will contain 2 and byte 21 will contain the specific error code. Refer to Table 3.15 below for
description of the possible error codes.
#
6 Word Input/Output Message
If an erroneous Parameter Access message is sent to the drive, the drive will respond with a fault message. The MSB of byte 4 of the fault
response will be set. If the fault is a read parameter data fault, byte 4 of the response message will contain 83h, read parameter function
code 03h with the MSB set. If the fault is a write parameter data fault, byte 4 of the response message will contain 90h, write parameter
function code 10h with the MSB set. Byte 7 will contain 2 and byte 9 will contain the specific error code. Refer to Table 3.15 below for
description of the possible error codes.
Table 3.15 – Parameter Access Fault Message Response
