Description

Category 1 definition

IEC/EN60204-1 defines category 1 emergency stop as a controlled stop with the
power to machine actuators available to achieve the stop and then removal of power
when the stop is achieved.

Implementation of category 1 stop in ACS800 in brief

After the emergency stop command has been given, the drive first decelerates the
motor to a standstill according to a preset ramp time. Then, the main contactor is
switched off.
