Stop Category 2

A controlled stop, with power left available to the machine actuators.
The machine receives the operational stop command (disable) and brakes the drive using
the set braking ramp (STOPMODE and ACTFAULT parameters set to "1").
}
The drive is braked in a controlled manner as it comes to a stop. If the speed VEL0
(see timing diagram in the section entitled "Switch on/switch off behaviour") drops be-
low the set value, the holding brake is applied and the servo amplifier is shut down. In
this case, the mains voltage is maintained.
}
If the mains is switched off, not only is a controlled braking procedure initiated but the
mains voltage is galvanically isolated from the holding brake after a delay, which can be
set on the timer.
