STO90 Parameters

3 STO90 PARAMETERS
The parameters of the CFW900 frequency inverter that are directly related to the STO90 safety
functions board are presented below.
S4 FUNCTIONAL SAFETY
Displays information related to the functional safety of CFW900.
S4 Functional Safety
1 State
.2 SS1-t Delay Time
.1 State Indicates the state of STO90.
Indication
0 = Not used Not used
1 = STO Indicates that STO90 is in the STO (Safe Torque Off) state
2 = Operational Indicates that STO90 is in operational state (torque enabled)
3 = Programming Indicates that STO90 is in programming mode (delay time)
4 = SS1-t Indicates that STO90 is executing the SS1-t (Safe Stop 1 - time controlled) function
5 = Fault Indicates that STO90 is in a fault state
.2 SS1-t Delay Time Indicates the delay time of the SS1-t safety function set in STO90.
C8 FUNCTIONAL SAFETY
Allows configuring parameters related to the functional safety of CFW900.
C8 Functional Safety
C8.1 SS1-t Ramp Deceleration Time
Range:
0.1 ... 999.9 s
Properties: Stopped
Description:
Defines the time in seconds to linearly decelerate the motor from the maximum speed to zero
during the execution of the SS1-t safety function.
NOTE!
This parameter should not be confused with the delay time of the SS1-t safety
function. For programming the delay time, please refer to the safety function
configuration in the safety manual.
NOTE!
If the SS1-t ramp deceleration time is set to a time value greater than the
programmed SS1-t delay time ( S4.2 ), the STO state will be reached before
the complete stop of the motor.
