If you use this approach for the FSPS-21 module, you can set the PROFIsafe cycle time
and the corresponding watchdog time F_WD_Time as short as possible for the given system.
If the longest recorded PROFIsafe cycle time (minimum F_WD_Time) is, for example, 40
ms, a suitable value for F_WD_Time is:
F_WD_Time = 40 ms x 1.3 = 52 ms.
Installation
Installation procedure:
1. Install the FSPS-21 safety functions fieldbus module to the drive, see chapters Planning
for installation and Installation and the drive hardware manual.
2. Connect the FSPS-21 module to the safety PLC through a PROFINET network.
Configuration
ï¿ Configuring the FSPS-21 module
You can use either the drive control panel or the Drive composer pro PC tool to modify the
settings of the FSPS-21 module.
Parameters for the PROFINET and PROFIsafe communication
1. Depending on the drive, you can configure the FSPS-21 module as fieldbus channel A
or B. Enable the communication between the drive and the FSPS-21 module for the
option slot in which the FSPS-21 module is installed into (parameter 50.01 FBA A enable
or 50.31 FBA B enable).
2. Set the FSPS-21 parameters that correspond to the selected fieldbus channel. Parameter
groups 51, 52 and 53 include the settings for FBA A and groups 54, 55 and 56 for FBA
B.
Groups 52, 53, 55 and 56 configure the contents of the normal PROFINET cyclic
communication by mapping the words in the PROFINET frame to the desired drive
parameters.
Groups 51 and 54 configure the PROFINET and PROFIsafe connection.
