3.3 Checking Steps
3-19
Free Curve Movements with FWD/BWD Operations
• The manipulator moves in a straight line to the first step of free curve motion.
• There must be three free curve motion steps in a row to perform a free curve operation.
• Depending on the position where the [FWD] / [BWD] operation is performed, the alarm
“IRREGULAR DISTANCES BETWEEN TEACHING POINTS” may occur. Note that FWD/
BWD inching operations change the path of the manipulator and
caution is therefore
required
. Performing these operations also increases the likelihood that the “IRREGU-
LAR DISTANCES BETWEEN TEACHING POINTS” will occur.
• If the [FWD] or [BWD] operation is restarted after being stopped to move the cursor or
perform a search, the manipulator moves in a straight line to the next step.
• If the [FWD] or [BWD] operation is restarted after being stopped to move the axis as
shown in the following, the manipulator moves in a straight line to P2, the next free curve
motion step. Free curve motion is restored from P2 onward. However, the path followed
between P2 and P3 is somewhat different from the path followed at playback.
• If the manipulator is moved to P3 with [FWD], stopped, and then returned to P2 with
[BWD], the path followed between P2 and P3 is different for each of the following: the first
FWD operation, the BWD operation, and the consequent FWD operation.
n
Selecting Manual Speed
When [FWD] or [BWD] is pressed, the manipulator moves at the manual speed selected at
that time. The set manual speed can be checked by the MAN SPD lamp on the programming
pendant.
Manual speed is set with [FST] and [SLW]. FWD operation can be performed at a high speed
by pressing [HIGH SPD]. Follow the procedure below to select a manual speed.
