8.5.3.7
Controlled stop, EMERGENCY STOP category 1
The EMERGENCY OFF function for controlled shutdown stops the drive by means of a quick
stop process along a deceleration ramp that must be parameterized.
Note
The drive is stopped during controlled deceleration without braking modules with only a very
low % braking torque. Depending on the load machine, the ramp-down procedure may take a
long time.
Connections of the EMERGENCY STOP button
Most of the contacts of the EMERGENCY STOP button are integrated in the control circuit of
the circuit-breaker. The two remaining normally-closed contacts of the EMERGENCY STOP
button are situated on the terminal block.
