Parameters involved
The following parameters are used in conjunction with the transition function
"Safe stop 1":
● P‑0‑3238, SMO: Active velocity threshold
● P‑0‑3255, SMO: Velocity threshold for Safe standstill
● P‑0‑3263.0.1, SMO: Configuration of stopping process
● P‑0‑3280.0.1, SMO: Configuration of operation mode transitions
● P‑0‑3280.0.2, SMO: Max. Transition time normal oper. to safe standstill
● P‑0‑3280.0.3, SMO: Max. Transition time between safe operating states
Diagnostic messages involved
The following diagnostic messages can be generated in conjunction with the
transition function "Safe stop 1":
● C0214 SMO: Incorrect configuration
● F7050 Maximum transition time exceeded
● F7051 Safely-monitored deceleration exceeded
● F8350 Maximum transition time exceeded
● F8351 Safely-monitored deceleration exceeded
With the transition function "Safe stop 1" activated, the display of the panel
does not show any specific message.
Transition function
Basic principle
When the transition function "Safe stop 1 (SS1)" is activated, the drive is
decelerated in a safely monitored way. After the deceleration process has been
completed, the safety function "Safe torque off (STO)" is activated and the
energy supply to the motor is safely interrupted. The motor cannot generate any
torque/any force and therefore no dangerous movements.
The transition function "Safe stop 1" detects a successful deceleration process,
if the following conditions have been fulfilled:
