Reference
Table 59: VELOCITY ON/OFF
VELOCITY
ON/OFF Velocity Mode Statement
Purpose The VELOCITY ON statement enables velocity mode in the drive. The VELOCITY OFF statement
disables velocity mode and returns drive to its default mode. (Default mode is Positioning). The
velocity value for this mode is set by writing to the System Variable “VEL”. All position related
variables are valid in this mode.
Syntax VELOCITY ON
VELOCITY OFF
Remarks The “VELOCITY ON” statement is considered one of the motion related commands. It has to be
implemented when the drive is enabled. If the “VELOCITY ON” statement is executed while the drive
is disabled, fault # 27-”Drive disabled” will occur.
Execution of any motion related profiles while the drive is in Velocity mode will be loaded into the
Motion Queue. When the “VELOCITY OFF” statement is executed the drive defaults back to Position
mode and immediately begins to execute the motion profiles stored in the Motion Queue. Please note
that the “VEL” variable can be set on the fly, allowing dynamic control of the velocity.
