which means maximum allowed motor speed (100%). In VACON
®
FBSpeedReference, the value is
between 0d - 10000d (100.00%) and in PROFIDrive NIST_A the value is between -16384d - 16384d.
Note also that when you use NSOLL_A, our minimum and maximum frequency parameters affect
the speed reference differently than when you use the FBSpeedReference directly. When you use
NSOLL_A, the PROFINET will give zero reference to the application until NSOLL_A exceeds the
minimum reference, but if you use the FBSpeedReference, the given value is always scaled between
the minimum and maximum frequency. For example, if the Minimum Frequency is 30 Hz and the
Maximum Frequency is 50Hz, the NSOLL_A value between 0 and 9830 will run 30Hz. If the
FBSpeedReference is used, then for example value 1000 (10%) will run 32Hz.
Telegrams contain different amount of process data items. Those vary from none to 16 items.
Process data can be 16 or 32 bits in size. Process data in VACON® NXP drives is only 16 bit, so
telegrams which use 32 bit process data have the upper 16 bits always as zero.
If you want to use more than 8 process data items, then the fieldbus option board communication
mode must be 'Fast mode with safety "black channel"', 'Fast Mode' or 'Normal Extended' mode. See
Chapter 16 "Appendix 6 - Fieldbus option board communication" for more information on the
communication mode.
8.3.2 Telegram types
8.3.2.1
Standard Telegram 1 and variants
Standard Telegram 1 types are used when a standard VACON
®
application is used and PROFIdrive
functionality is required. These telegrams (Table 49) use PROFIdrive-defined control word, status
word, speed setpoint value and speed actual value. When using these telegrams, the process data
fields are communicated as 16-bit values.
STW1 will force edge sensitive run control.
NOTE! When a board is connected to VACON
®
100 family AC drive and its mode parameter is set to
“NX Mode”, the option board will use FBSpeedReference/FBSpeedActual instead of NSOLL_A/
NIST_A as backward compatibility for OPTCP option board.
* 12 and 16 process data items are available in VACON
®
NXP AC Drive. See Chapter 16 "Appendix 6 -
Fieldbus option board communication".
