4. HOW TO USE THE POINT TABLE
4 - 5
4.1.5 Point table setting
Set the data for operation to the point table. The following shows the items to be set.
Item Main description
Position data Set the position data for movement.
Servo motor
speed
Set the command speed of the servo motor for execution of positioning.
Acceleration
time constant
Set the acceleration time constant.
Deceleration
time constant
Set the deceleration time constant.
Dwell Set the waiting time when performing automatic continuous operation.
Auxiliary function Set when performing automatic continuous operation.
M code
Outputs the first digit and the second digit of the M code in 4-bit binary
respectively.
Refer to section 4.2.2 for details of the point table.
4.1.6 Actual operation
Start actual operation after confirmation of normal operation by test operation and completion of the
corresponding parameter settings.
4.1.7 Troubleshooting at start-up
CAUTION
Never make a drastic adjustment or change to the parameter values as doing so
will make the operation unstable.
POINT
Using MR Configurator2, you can refer to the reason for rotation failure, etc.
The following faults may occur at start-up. If any of such faults occurs, take the corresponding action.
"MR-J4-_A_" means "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual".
No. Start-up sequence Fault Investigation Possible cause Reference
1 Power on The 7-segment LED
display does not turn
on.
The 7-segment LED
display flickers.
Not improved even if CN1, CN2,
and CN3 connectors are
disconnected. 1. Power supply voltage fault
2. The servo amplifier is
malfunctioning.
Improved when CN1 connector is
disconnected. Power supply of CN1 cabling is
shorted.
Improved when CN2 connector is
disconnected. 1. Power supply of encoder
cabling is shorted.
2. Encoder is malfunctioning.
Improved when CN3 connector is
disconnected. Power supply of CN3 cabling is
shorted.
Alarm occurs. Refer to chapter 8 and remove the cause. Chapter 8
(Note)
2 Switch on SON
(Servo-on). Alarm occurs. Refer to chapter 8 and remove the cause. Chapter 8
(Note)
Servo motor shaft is
not servo-locked.
(Servo motor shaft is
free.) 1. Check the display to see if the
servo amplifier is ready to
operate.
2. Check the external I/O signal
indication (section 3.1.7 or
3.2.7) to see if SON (Servo-
on) is on.
1. SON (Servo-on) is not input.
(wiring mistake)
2. 24 V DC power is not supplied
to DICOM.
