[2] Precautions for control
(1) At the set speed of 1 (pulse/s), the set acceleration/deceleration time is
ignored.
(2) In the acceleration/deceleration pattern where the movement amount is
small relative to the acceleration/deceleration time and a constant-speed
part does not exist, operation is not performed at the set
acceleration/deceleration time. In such a case, review the setting details.
(3) If operation is performed with 0 set as the bias speed at start in the control
method of "1-axis linear control (ABS)" or "1-axis linear control (INC)"
positioning control, an error "Movement amount shortage at 0 bias speed"
(error code: 514) may occur due to shortage of the movement amount.
Perform either of the following operations (a), (b) as the corrective action at
error occurrence.
(a) Set 1 (pulse/s) or more to "
Pr. 6
bias speed at start".
(b) If the movement amount is 32 (pulse) or less, set the value equal to or
less than the initial value (1000ms) to "
Da. 3
ACC/DEC time" and
"
Da. 4
DEC/STOP time".
