Caution - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

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 operation decelerates and
stops after the input interrupt occurs. After deceleration stop, the output direction is reversed to the address where the
positioning address was changed and the operation ends normally.
• 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.
Speed
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.
2.
When the number of pulses required for deceleration from the current speed ≤ positioning address < the number of
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.
3.
When the number of pulses required for acceleration/deceleration from the current speed ≤ positioning address
The speed is increased to the command speed (s2). Then, deceleration stop is performed.
