Parameters 213
31.33 Emergency ramp
supervision delay
If parameter 31.32 Emergency ramp supervision is set to
0%, this parameter defines the maximum time an
emergency stop (mode Off1 or Off3) is allowed to take. If
the motor has not stopped when the time elapses, the
drive trips on 73B0 Emergency ramp failed, sets bit 8 of
06.17 Drive status word 2, and coasts to a stop.
If 31.32 is set to a value other than 0%, this parameter
defines a delay between the receipt of the emergency
stop command and the activation of the supervision. It is
recommended to specify a short delay to allow the speed
change rate to stabilize.
