Deceleration Value Selecting
Selects either acceleration value (symmetry acceleration/deceleration) or deceleration value individually (non-symmetry
acceleration/deceleration) as a deceleration speed at deceleration in trapezoidal driving.
Display Option
Default
Deceleration Value
Accel (Acceleration) / Decel (Deceleration)
Accel
MR210AU/220AU can perform not only symmetry
acceleration/deceleration driving where the
acceleration and the deceleration are same but also
non-symmetry acceleration/deceleration driving
where the acceleration and the deceleration are
different. When selecting Accel (Acceleration), the
acceleration parameter is used as a deceleration speed
at deceleration and driving becomes symmetry
trapezoidal. When selecting Decel (Deceleration), the deceleration parameter is used as a deceleration speed and driving
becomes non-symmetry trapezoidal.
[Note]
Please note that the following (1), (2) for when non-symmetry trapezoidal acceleration/deceleration driving is performed.
(1) In the case of acceleration > deceleration, the following condition is applied to the ratio of the acceleration and the
deceleration.
For instance, if driving speed V = 100kps, deceleration D must be greater than 1/40 of acceleration A. The value must not be less
than 1/40 of the acceleration.
(2) If acceleration > deceleration, the greater the ratio of acceleration A to deceleration D becomes, the greater the number of creep
pulses (outputs of specified driving pulses are not completed at deceleration of index driving even if the speed reaches the
initial-speed and remaining driving pulses are output at initial-speed.) becomes. Approximately maximum of 10 pulses when
A/D=10 times.

Software Limit
Selects either Disable or Enable for software limit.

Soft Ware Limit

Software Limit is the over run limit function which can internally set as position data; it differs from hardware limit signal input
such as an external sensor. Software limit can be set as parameters for + and – direction respectively. When selecting enable, and
when the position counter is over the software limit + to – range during driving, decelerating stop will be performed. This error
condition will be cleared if the user drives in the opposite direction and sets the position counter back within a software limit
range.
[For reference] While a home search is running, the software limit does not function even if enabled.

Power On Home Search Start
Selects either Disable or Enable for automatic home search at power-on.
Display Option
Default
Power On Home Search Start
Disable / Enable
Disable
Power On Home Search Start is the function to automatically perform home search when the power is on or motor control unit is
reset.
