With triggering SS1 (Safe Stop 1), the motor is only switched torque-free when it
has reached standstill [EN 61800-5-2]. The idle state is not queried directly, but the
maximum time until the standstill is reached is estimated.
This time period is loaded into a safe time relay that finally switches the motor
torque-free.
When the emergency stop device is actuated, the motor is brought to a standstill
with a deceleration ramp via input X2A.13 (I7).
At the same time, the safe time expires in the safety module. After the safe time
has elapsed, the control signals STO1+ and STO2+ (X2B.2 and X2B.4) are
switched off and by way the energy supply of the motor is interrupted.
A suitable parameterisation of the control is necessary for the function "Stop
drive".
