Fault Type(s):
1 = The motor moved more

parameter, Motor_Not_

setting.
2 = The motor moved faster
than the parameter, Motor_
Not_Stopped_Speed_Error
(RPM) for 160 ms.
3 = The three-phase drive
has applied an electrical
frequency greater than the
Motor_Not_Stopped_Max_
Frequency parameter, and
applied an RMS current
greater than the Motor_
Not_Stopped_Max_Current
parameter for 64 ms.
1. Misadjusted Motor Not
Stopped parameters.
2. See: Programmer » Application
Setup » Motor Not Stopped menu.
3. Internal Controller fault or conict
allowing the motor to rotate when
in the stopped state.
Set: Motor Not Stopped is a
safety function implemented in
the Primary microprocessor on
a category 2 architecture per
ISO 13849. The purpose of this
function is to detect hazardous
movement when the AC motor
is stopped and expected to
stay stopped (i.e., no throttle
command). There are three
main checks done when
the motor is in the stopped
state, each of which can be
independently enabled and
each of which has a unique
fault type.
