12 PROFIdrive profile (V4)
12.1 What is PROFIdrive profile?
The PROFIdrive profile is a non-vendor specific standard for controlling drives.
PROFIdrive allows compatible drives from different vendors to be controlled and
monitored using the same control strategy.
For further details of the PROFIdrive profile refer to the official PROFIBUS web-site at
www.profibus.com.
The SI-PROFIBUS module provides support for the “Standard Drive” application class 1
defined in the PROFIdrive V4 specification for speed control mode using Standard
Telegram 1.
SI-PROFIBUS supports the following PROFIdrive features:
• Standard Telegram 1
• PROFIdrive PNU Access
• Drive Identification
• Fault Buffer
• Identification and Maintenance Functions
12.2 Standard Telegram 1
To select the Standard Telegrams, the following sequence must be performed:
•Set Pr S.01.030 to "None" to disable non-cyclic data over the cyclic channel.
•Set Pr S.01.014 to "16" to set data alignment to 16 bits.
•Set Pr S.01.008 to "STD Tel 1".
•Pr S.01.002 or MM.007 set to “On” to reset the SI-PROFIBUS module.
• Check Pr S.01.006 does not display any errors (see Table 6.4 on page 32 for
further details).
• Save drive parameters (refer to relevant drive documentation for more
information).
The Standard Telegram 1 mode may also be configured automatically by the master
controller if Pr S.01.008 is set to Auto.
The Standard Telegram 1 support is a mandatory requirement for Application Class 1
devices, the mapping structure is shown Table 12.1.
Table 12.1 Standard Telegram 1 - mapping structure
Pr S.01.002 or MM.007 will automatically revert to ‘Off’ after resetting. Resetting will
cause the SI-PROFIBUS to temporary go off-line from the PROFIBUS-DP network.
After the PROFIdrive profile has been configured and the module reset, if no
configuration error is detected then the corresponding mapping parameters will be set
automatically by the master controller; i.e. Pr S.02.001 = 5.00.968; Pr S.02.002 =
5.01.001; Pr S.03.001 = 5.00.967 and Pr S.03.002 = 5.01.003
