SIMOVERT MASTERDRIVES
P721 (CB parameter 11)
Special CAN bus settings
This parameter is only present in MASTERDRIVES units from the following
software versions onwards:
MASTERDRIVES
SIMOVERT MASTERDRIVES MC
SIMOVERT MASTERDRIVES FC
SIMOVERT MASTERDRIVES VC
SIMOVERT MASTERDRIVES SC
SIMOVERT MASTERDRIVES E/R
SIMOVERT MASTERDRIVES AFE
•
Index i001: With this parameter, different CAN profiles can be set in
future. At the present time, only the value 0 (pre-assigned) is valid.
•
Index i002: With this parameter, the bus timing on the CAN bus can be
influenced. With the value 0 (pre-assigned), the internal setting resulting
from the baud rate is made. All other values are directly set without a
plausibility check.
This parameter should generally be allowed to keep its pre-assigned setting
of 0!
Meaning of the parameter-value bits:
Bit0 - Bit5: BRP (Baud rate prescaler).
Bit6 - Bit7: SJW SJW (Synchronization Jump Width). Maximum shortening
or lengthening of a bit time by means of resynchronization.
Bit8 - Bit11: TSEG1 (Time Segment 1). Time intervals before the scanning
time. Valid values are 2 to 15.
Bit12 - Bit14: TSEG2 (Time Segment 2). Time interval after the scanning time.
Valid values are 1 to 7. In addition TSEG2 must be greater than
SJW.
Bit 15: Not assigned
Internal standard pre-assignments of the bus timing, depending on the baud
rate:
Baud rate
10 kBit (P720/P705 = 0)
20 kBit (P720/P705 = 1)
50 kBit (P720/P705 = 2)
100 kBit (P720/P705 = 3)
125 kBit (P720/P705 = 4)
250 kBit (P720/P705 = 5)
500 kBit (P720/P705 = 6)
800 kBit (P720/P705 = 7)
1 MBit (P720/P706 = 8)
