Basic Move Types (continued)
CW/CCW Jog Move (continued)
As shown below, a Jog Moves begins at the programmed Starting Speed, accelerates at the programmed rate
to the Programmed Speed and continues until a stop condition occurs. If it is a
Controlled Stop Condition , the
Networked Driver will decelerate the motor to the starting speed and stop without losing position. If it is an
Immediate Stop Condition , the motion stops immediately and the position becomes invalid.
It is possible to change the speed of a Jog Move without stopping the motion. The Programmed Speed, Accel-
eration, and Deceleration parameters can be changed during a Jog Move. When the Programmed Speed is
changed, the motor will accelerate or decelerate to the new Programmed Speed using the new accelerate/
decelerate parameter values. If you write a Programmed Speed to the unit that is less than the starting speed,
the Jog Move will continue at the previously programmed speed.


A CW or CCW Limit Switch is reached. If the limit that is reached is the same as the direction of travel,
for example, hitting the CW limit while running a CW move, a
Reset Errors command must be issued
before moves are allowed in that direction again. If the limit that is reached is opposite the direction of
travel, a
Reset Errors command does not have to be issued.
Note that it is possible to start a move while a CW or CCW Limit Switch is active as long as
the direction of travel is opposite that of the activated Limit Switch. For example, it is possible
to start a CW Jog Move while the CCW Limit Switch is active.
