Precautions for Correct Use Precautions for Correct Use
• During the homing operation, the stop function for the Stop Selection for Drive Prohibition
Input is disabled.
• When the Drive Prohibition Input Selection (3504 hex) is set to 0, a Drive Prohibition Input
Error 1 (Error No. 38.0) will occur if the drive prohibition input is detected on both sides.
• When the Drive Prohibition Input Selection (3504 hex) is set to 1, a homing error (Home error)
1 will occur when the drive prohibition input is detected on both sides.
If this Homing method is used without using the drive prohibition input, do not assign the drive
prohibition input to a general-purpose input.
For details on assigning the general-purpose input signals, refer to 7-1 Sequence I/O Signals
on page 7-2.
• When the Drive Prohibition Input Selection (3504 hex) is set to 2, a Drive Prohibition Input
Error 1 (Error No. 38.0) will occur if the drive prohibition input is detected on one side.
When using this Homing method, set the Drive Prohibition Input Selection (3504 hex) to a value
other than 2.
 Homing Methods 33 and 34: Homing with an Origin Signal
In these Homing methods, only the origin signal is used.
The operation start direction of the homing operation is the negative direction in Homing method 33
and the positive direction in Homing method 34.
A homing error (Home error) 1 will occur in the following cases.
• When the drive prohibition inputs on both sides are ON at the same time.
• If no origin signal is detected before the drive prohibition input of the drive direction turns ON.
