Description Example value Name Index
Sets the type of the safety pulse encoder interface
module 1. FSE-31 Module 1 type 91.11
Sets the slot in which the safety pulse encoder interface
module 1 is located. 2 Module 1 location 91.12
Activates or deactivates the communication with the
safety pulse encoder interface module 1 and sets the
type for the safety pulse encoder. HTL1 Encoder 1 type 92.01
Sets the safety pulse encoder interface module that
the safety pulse encoder 1 is connected to. Module 1 Encoder 1 source 92.02
Sets the number of HTL pulses per revolution for safety
pulse encoder 1. 2048 Pulses/revolution 92.10
Adjust the default value to meet the safety pulse en-
coder in use. Make sure that the value is according to
the encoder nameplate.
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 · ppr_enc + 10%, where
300 kHz Accepted pulse freq
of encoder 1 92.17
• r_max : the maximum motor speed (rpm) used in the
application (or the motor nominal speed)
• ppr_enc : pulses/revolution of the safety pulse en-
coder (parameter 92.10 ).
Mechanical brake control
If you use a mechanical brake with the motor thermal protection circuit, pay special attention
to the control of the mechanical brake.
If the motor deceleration by the mechanical brake causes extra heat generation in the Ex
zone, make sure that the use of the brake does not increase the temperature too much. In
this case, make sure that the mechanical brake is activated only at zero speed (see
parameters
SBC.11 , SBC.15 and FSOGEN.51 or FSOGEN.52 ).
In some cases you cannot use the brake for the motor deceleration when the motor thermal
protection circuit has tripped and the motor temperature is too high.
For more information, see the drive firmware manual (or the FSO module user’s manual if
you use the Safe brake control (SBC) function of the FSO module).
