Acceleration/Deceleration time constant
The initial setting of this parameter is 900 (min
–1
/sec).
Please set and adjust this parameter depends on the motor output
torque and spindle inertia.
Please refer to the section of parameter explanation (Subsec.
1.2.5) in details.
(b) Limitation of regenerative power
(In case of this data is too small, the deceleration time is
increased.)
