FSE module and safety pulse encoder parameters
Set these parameters when you use a safety pulse encoder in the safety application.
Index Name Example
value Description
200.231 FSE 3X act and
par version
Version 1 Activates the FSE-31 encoder interface and shows the
version of the encoder parameter groups (91 and 92).
200.232 Number of
encoders
Single
encoder
CH1 Shows the number of safety pulse encoders connected to the
FSE module.
S_ENCGEN.01 Safe pulse
encoder version
Version 1 Activates the safety pulse encoder and shows the version
parameter group S_ENCGEN.
S_ENCGEN.11 FSE diagnostic
failure reaction
STO Sets the action taken when there is a problem with the FSE
module.
STO : The FSO module goes into the Fail-safe mode and
activates the drive STO function.
Note : This parameter is relevant only when there are no
active safety functions.
S_ENCGEN.14 Enc speed cross
comp tolerance
1 rpm Sets the encoder speed cross comparison tolerance. This
defines how much the axle speed of the motor can change
within 1 ms.
Adjust the default value to meet the motor in use.
S_ENCGEN.41 Gear numerator
encoder 1
1 Sets the rotation direction for the safety pulse encoder.
With this parameter, you can change the rotation direction of
the motor.
Adjust the default value if necessary.
91.11 Module 1 type FSE-31 Sets the type of the safety pulse encoder interface module 1.
91.12 Module 1 location 2 Sets the slot in which the safety pulse encoder interface
module 1 is located.
92.01 Encoder 1 type HTL1 Activates or deactivates the communication with the safety
pulse encoder interface module 1 and sets the type for the
safety pulse encoder.
92.02 Encoder 1 source Module 1 Sets the safety pulse encoder interface module that the
safety pulse encoder 1 is connected to.
92.10 Pulses/revolution 2048 Sets the number of HTL pulses per revolution for safety
pulse encoder 1.
Adjust the default value to meet the safety pulse encoder in
use. Make sure that the value is according to the encoder
nameplate.
92.17 Accepted pulse
freq of encoder 1
300 kHz Sets the maximum pulse frequency range of encoder 1.
Adjust the default value to meet the motor and safety pulse
encoder in use. You can use this formula to define the value:
r_max x p 10%, where
• r_max = the maximum motor speed used in the application
(or the motor nominal speed)
• ppr_enc = Pulses/revolution of the safety pulse encoder
(parameter 92.10 ).
