ABB ACS880-17 User Manual

52 Parameter settings
In addition to the parameters related to the SS1 function, change or set the value of these
parameters.
SS1 ramp parameters in the drive/inverter unit
You must set these parameters only for the SS1 function.
If FSO parameter 200.112 SAR1 ramp time to zero is set to 0, drive parameters define the
stop ramp that is used in the SS1 function:
• 21.04 Emergency stop mode is set to value Eme ramp stop (Off3)
• 23.23 Emergency stop time is set to a suitable value.
Also in this case, the FSO module monitors the actual stop ramp (ramp monitoring or time
monitoring). For more information, see the firmware manual.
 FSE module and safety pulse encoder parameters
Set and check these parameters only when you use a safety pulse encoder and the FSE-
31 pulse encoder interface module with the FSO-21 module.
Index Name Pre-set value
(STO function)
Value with the SS1 function
STO.12 STO input B DI X113:4 None
FSOGEN.51 Zero speed without
encoder
90 rpm If you do not use a safety encoder, adjust the
default value to meet the motor in use.
FSOGEN.52 Zero speed with
encoder
0 rpm If you use a safety encoder, adjust the default
value to meet the motor in use.
FSOGEN.62 STO indication safety
limit
Fault Adjust the default value when necessary.
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 ratings of
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.
