●
The motor control mode and acceleration / deceleration time can be selected separately. The acceleration /
deceleration time is the time set in F1012
-
F1021. (no external signal is required)
●
With the speed control mode (F1001=2 or 3), the output current can still be limited by the torque limiter even the
function of output current limiting at constant speed is OFF. Also, even if the function of output current limiting
at constant speed has been set (F1703=1
-
9), when the limit value on the torque limiter is low, the situation of
using a current limit lower than the values set in F1701 can still happen.
Note 1: The code for limiting actions of output current at constant speed and the code for selecting of normal 1st - 4th
acceleration/deceleration time share the same code.
Note 2: The situation that the output current is limited by speed control through the torque limiter may be used in case
that the values set in F1012-F1021 don’t decelerate.
Note 3: Use torque control mode, this function won’t work since the control methods are different.
