Sets the encoder speed cross comparison
tolerance. This defines how much the axle
speed of the motor can change within 1 ms.
1 rpm
Enc speed cross
comp tolerance
S_ENCGEN.14
Adjust the default value to meet the motor
in use.
This parameter is used for the encoder
diagnostic. It defines how big the difference
between the speed information from chan-
nel A and B of the encoder can be. If the
difference of these two values is bigger than
value set to this parameter, FSO will safely
stop the system (STO).
The suitable value depends on the configur-
ation (motor / load). Typically this value is
2-10 rpm, too small value will cause en-
coder fault (A7D8) and too big value will
prevent encoder diagnostic related to this
parameter.
Sets the rotation direction for the safety
pulse encoder.
1
Gear numerator en-
coder 1
S_ENCGEN.41
With this parameter, you can change the
rotation direction of the motor.
Adjust the default value if necessary.
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 en-
coder 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 revolu-
tion for safety pulse encoder 1.
2048
Pulses/revolution
92.10
Adjust the default value to meet the safety
pulse encoder in use. Make sure that the
value is according to the encoder name-
plate.
Sets the maximum pulse frequency range
of encoder 1.
300 kHz
Accepted pulse freq
of encoder 1
92.17
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 × 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).
