Function inputs
Parameter Description
X stop
request sel
Selects the variable that is inverted and then used to drive X
stop active. The variable selected by X stop request sel must be
False to initiate an X-stop.
Variable Description
X stop
request, lan
Is used to drive X stop active from the LAN when LAN
commands OK is True. X stop request, lan must be True to
initiate an X-stop. Please note that this is OPPOSITE the
behavior of X stop request sel. (See also LAN Signal Map.)
Function output
Variable Description
X stop active
Causes drive to perform an X-stop as configured by X stop
mode. It also drops out the Ready to run permissive string.
Function configuration
Parameter Description
X stop mode Selects the behavior of an X-stop. Possible choices are:
Nrml (ramp) stop
Quick stop
Coast stop
Trip flt stop
Emerg ramp stop
(See below.)
Function description
An X-stop can have 1 of 5 stopping behaviors as configured by the parameter X stop
mode.
Nrml (ramp)
stop
The drive follows a linear speed deceleration ramp down to zero
speed as configured by the Speed Reference Ramp function. Once
the drive detects that Speed reg fbk has reached the Zero speed
level, the sequencer disables the regulators and stops the drive.
Quick stop The speed reference is stepped to zero so that the speed is brought
to zero as quickly as possible (the drive is in current limit). Once the
drive detects that Speed reg fbk has reached the Zero speed level,
the sequencer disables the regulators and stops the drive.
Coast stop
The regulators are immediately disabled and power is removed from
the motor so that it will coast to a stop. The sequencer will prevent
the drive from being re-started until Speed reg fbk has reached the
Zero speed level, unless Flying restart is enabled.
Trip flt stop
Behavior is similar to that of a Coast stop, except that a Trip fault, X
stop, is also generated.
Emerg ramp
stop
The drive follows a linear speed deceleration ramp down to zero as
configured by the parameter Emerg ramp rate. (See also the Speed
Reference Ramp.) Once the drive detects that Speed reg fbk has
reached the Zero speed level, the sequencer disables the regulators
and stops the drive.
Once the drive is stopped, X stop active must be set False before the drive is re-
started. Otherwise, if any type of run is requested, the sequencer will generate an Run
req & xstop open trip fault.
