• When the operation direction inverts after the target address is changed
After the target address is changed, the motor decelerates and stops once, and then starts rotation in the
reverse direction within 1 ms in the case of forward pulse/reverse pulse output or within 2 ms in the case of
pulse/direction output.
Target address
change value
(BFM#54, #53)
*1.
In the case of forward pulse/reverse pulse output: Within 1 ms
In the case of pulse/direction output: Within 2 ms
3. Update time for the target address change value
After the target address change value is updated, the time required until the target address is changed will be
as follows.
• During operation at 1 kHz or higher: Within 3 ms
• During operation at less than 1 kHz: Within 3 pulses
Caution when the target address change function is used
• In the following conditions, writing a value to the target address change value does not validate the target
address change. No error will occur either.
- During deceleration by the STOP command (STOP, forward limit, reverse limit)
- During deceleration and stopping of the positioning operation
- Operation that the target address change function cannot be used
- During use of the approximate S-shaped acceleration/deceleration function
- After interrupt input detection of the interrupt stop operation
- When changing to the target address that requires inverting during the interrupt 1-speed positioning
operation or the interrupt 2-speed positioning operation
- During remaining distance operation waiting (remaining distance operation is cancelled)
• When no change in operation direction occurs after the target address change
- When the travel distance from the positioning operation start position to the target address after the
change exceeds ±32 bit, the deceleration stop is executed at the position where the target address is
changed. The set value overflow error occurs.
• When the operation direction inverts after the target address change
- When the travel distance from the deceleration stop position to the target address after the change
exceeds ±32 bit, it stops at the deceleration stop position. The set value overflow error occurs.
