No.
How can the deceleration stop
time during stopping be shortened
using the hardware stroke limit?
Set "1: Sudden stop" in the "
Pr.37
Stop group 1 sudden
stop selection", and reduce the setting value of "
Pr.36
Sudden stop deceleration time".
11
The motor does not operate at
"60000ms" although the
acceleration/deceleration time is
set to "60000ms".
The value set for the acceleration/deceleration time is the
time required for the machine to accelerate from speed
"0" to the value set in "
Pr.8
Speed limit value". Because
of that, the acceleration/deceleration time will also be
shorter than "60000ms" if the command speed value is
smaller than the "
Pr.8
Speed limit value". (Refer to the
explanation for
Pr.9
and
Pr.10
for details.)
12
Can each acceleration/
deceleration time be individually
set to trapezoidal or S-pattern
acceleration/deceleration?
The trapezoidal and S-pattern acceleration/deceleration
processing is a common setting for all
acceleration/deceleration times, so individual setting is not
possible.
(Refer to Section 12.7.7 "Acceleration/deceleration
process function".)
13
Acceleration/decelerat
ion time
The machine starts and stops
suddenly when carrying out JOG
operations and positioning
operations.
(Using an MR-J2S servo
amplifier.)
Review the parameter settings for acceleration/
deceleration time, speed limit value, JOG speed limit
value, JOG acceleration/deceleration time, etc.
14
Simplified absolute
value
Are simplified absolute values
possible in the QD75P and QD75D
Positional deviation models?
They are possible if the models are used in combination
with a Mitsubishi "AC Servo".
(Refer to "AC servo User's Manual" for details.)
15
Positional deviation
The physical position deviates
from the commanded position,
although the positioning is
complete (and the monitored
current position is correct).
If the deviation counter value is not "0", the servo side is
still moving.
Increase the torque.
16
Electronic gear
A setting of "1
µ
m 1PLS" is
required in the following system.
•
Ball screw pitch 10mm
•
No. of feedback pulses
8192PLS
In this case, the following values will result.
•
No. of pulses per rotation 8192
•
Movement amount per rotation 10000
•
Unit
magnification 10
Therefore, the "Movement amount per pulse" will become
"1.2207
µ
m".
This value is fixed by the machine system, so it cannot be
changed.
Thus, the setting "1
µ
m 1PLS" cannot be achieved.
