The forward and reverse position reference limits are used to set the roll-over position.
When rotating in the forward direction, the position reference rolls over to the reverse
position limit after reaching the forward position limit. When rotating in the reverse
direction, the position reference rolls over to the forward position limit after reaching
the reverse position limit.
Pn81D is the home position. Alarm, E16A, will occur if Pn81D is outside the posi-
tion reference limits (Pn81D>|Pn81B, Pn81C|) when pn81A=1, 2, or 3.
3. Pn81A=2=Rotary (Forward): Used for rotary motion.
Absolute move commands rotate in the forward direction only.
The forward and reverse position reference limits are used to set the roll-over position
(same as Pn81A=1).
4. Pn81A=3=Rotary (Reverse): Used for rotary motion.
Absolute move commands rotate in the reverse direction only.
The forward and reverse position reference limits are used to set the roll-over position
(same as Pn81A=1).
Servomotor Stop Mode for Hardware Overtravels (P-OT and N-OT)
Set the following parameters to specify the Servomotor Stop Mode when P-OT and N-OT
input signals are used.
Specify the Servomotor Stop Mode when either of the following signals are input during
servomotor operation.
• Forward run prohibited input (P-OT,CN1-42)
• Reverse run prohibited input (N-OT,CN1-43)
