Delay
Ramp (slope) Select this option to request a SS1
to decelerate at least with the
steepness of the deceleration ramp,
even under heavy load. The safety
option initiates a stop signal to
drive and monitors the controlled
braking by monitoring the braking
ramp.
Ramp (time) Select this option to enable a SS1
safety option with a deceleration
time and tolerable speed.
Function:
Linear The ramp follows a linear curve.
S-ramp Const The ramp follows a S-ramp.
Time
Function:
[0.1 - 3600 s] Configure the time during which
STO must be activated.
Function:
[0 - 99 %] Δ T subtracts from the time in
parameter 42-42 Delay Time to get
motor to stop before the timer
expires.
Function:
[1 - 30000 /s] Deceleration rate for the SS1 slope-
based ramp type.
Function:
[1 - 10000 Tolerance between calculated and
*
RPM] actual speed that the safety option
allows.
Function:
[1 - 600 When this speed is reached, the
RPM] safety option activates the STO.
Function:
[0.1 - 3600 s] Time to ramp down to 0 RPM.
