STOP MOTION [QUICK] Stop Motion Statement
Purpose
Stop (abort) motion immediately with deceleration rate set by DECEL System Variable
or QDECEL Variable if QUICK modifier is used and flash contest of the Motion
Queue. Main usage for controlled emergency stop or when End Of Travel sensor is
detected. Current position will be not lost after execution of this statement.
Syntax
STOP MOTION ;stops using DECEL deceleration rate
STOP MOTION QUICK ;stops using QDECEL deceleration rate

VELOCITY ON/OFF Velocity Mode Statement
Purpose
VELOCITY ON enables velocity mode. VELOCITY OFF disables velocity mode and
returns SSi to default mode. (Default mode is Indexing). Velocity value for this mode is
set by setting System Variable VEL. All position related variables are valid in this
mode.
Syntax VELOCITY
ON
VELOCITY OFF
Remarks
VELOCITY ON statement considered one of the motion related commands. It has to
be used when drive enabled. If VELOCITY ON statement is met when drive is
disabled fault # 27-"Drive disabled".
Execution of any motion related statement while in Velocity mode causes SSi to put
motion commands to Motion Queue. After execution of GEAR OFF statements SSi
returns to default Indexing mode and start execute motion commands from Queue
immediately. Note that VEL variable can be set on the fly, which allows dynamic
control of the velocity.
