Caution
• When 0 is set for the positioning address (s1) at start of the instruction, the operation ends with an error.
• If the positioning address (s1) is changed to 0 before the interrupt input signal 1 is detected, the positioning operation
continues and ends normally after the input interrupt occurs and two pulses are output.
• If the positioning address (s1) is changed to 0 after the interrupt input signal 1 is detected, the operation decelerates to a
stop, the output direction is reversed, and the operation continues before ending normally at the positioning address where
the input interrupt occurred.
• When transfer time to the positioning address is shorter than the time required for deceleration stop (the value set in (s1) is
small), the operation immediately stops at the positioning address. Note that the immediate stop may damage the machine
because the motor stops immediately.
Interrupt input signal 1
• When the interrupt input signal 1 is detected during acceleration, the operation differs depending on the positioning address
value (s1) as shown below.
(1) When the positioning address < the number of pulses required for deceleration from the current speed
After the interrupt input signal 1 is turned on, deceleration immediately starts, and then the operation immediately
stops when the positioning address is reached. Note that the immediate stop may damage the machine because the
motor stops immediately.
When the number of pulses required for deceleration from the current speed  positioning address < the number of
(2)
pulses required for acceleration/deceleration from the current speed
The speed is increased until the position at which the remaining number of pulses becomes the same as that
required for deceleration. Then, deceleration stop is performed.
When the number of pulses required for acceleration/deceleration from the current speed  positioning address
(3)
The speed is increased to the command speed (s2). Then, deceleration stop is performed.
