No.
Acceleration/
deceleration time
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-curve
acceleration/deceleration?
The trapezoidal and S-curve acceleration/deceleration
processing is a common setting for all
acceleration/deceleration times, so individual setting is not
possible.
(Refer to Section 12.7.6 "Acceleration/deceleration
process function".)
13
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
position detection
system
Are simplified absolute position
detection system possible in the
QD75 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 position
detection system 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
m 1pulse" is
required in the following system.
Ball screw pitch 10mm
No. of feedback pulses
8192pulse
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
m".
This value is fixed by the machine system, so it cannot be
changed.
Thus, the setting "1
m 1pulse" cannot be achieved.
