Cause and description
At the machine OPR using the stopper method 2, Zero
signal has turned off while the speed is decelerating from
OPR speed to creep speed.
[Operation of when the error has occurred]
The operation stops according to the setting of [Pr.39]
Stop group 2 sudden stop selection of detailed parameter
3 (deceleration stop/sudden stop).
At the machine OPR using the stopper method 1, the
dwell time has passed while the speed is decelerating
from OPR speed to creep speed.
[Operation of when the error has occurred]
The operation stops according to the setting of [Pr.39]
Stop group 2 sudden stop selection of detailed parameter
3 (deceleration stop/sudden stop).
At the machine OPR using the count method 1 or 2, the
distance set in [Pr.50] Setting for the movement amount
after near-point dog ON is shorter than the distance
required from the [Pr.46] OPR speed to the deceleration
stop.
[Operation of when the error has occurred]
The machine OPR is not started.
OPR request flag is on at the fast OPR start (Positioning
start No. 9002).
[Operation of when the error has occurred]
The fast OPR is not started.
Restart command has been turned on after the machine
OPR stop with Stop signal.
[Operation of when the error has occurred]
The operation does not restart.
Near-point dog signal has turned on and the hardware
stroke limit switch in the OPR direction has turned off at
the OPR using the near-point dog method.
[Operation of when the error has occurred]
The operation stops according to the setting of [Pr.39]
Stop group 2 sudden stop selection of detailed parameter
3 (deceleration stop/sudden stop).
Communication with a servo amplifier failed during
absolute position restoration using the dedicated
instruction.
[Operation of when the error has occurred]
The absolute position restoration is not performed.
The value outside the setting range is set in [Cd.17] JOG
speed at the JOG start.
[Operation of when the error has occurred]
The JOG operation is not performed.
The value to meet the setting condition is not set in
[Cd.16] Inching movement amount. (The setting value is
large.)
■Setting conditions
(Inching movement amount)  (A) ≤ (JOG speed limit
value)
The value of (A) is as follows.
• When the unit setting is pulse: 562.5
• When the unit setting is a value other than pulse: 337.5
[Operation of when the error has occurred]
The inching operation is not performed.
Action
• Slow down the OPR speed. For details, refer
toPage 402 [Pr.46] OPR speed.
• Input Zero signal while the object is moving at creep
speed when inputting the signal from an external
source. For details, refer toPage 81 Stopper
method 2.
• Slow down the OPR speed. For details, refer
toPage 402 [Pr.46] OPR speed.
• Set a greater value in [Pr.49] OPR dwell time. For
details, refer toPage 404 [Pr.49] OPR dwell time.
• Calculate the movement amount of the object from the
speed limit value, OPR speed, and deceleration time,
and set [Pr.50] Setting for the movement amount after
near-point dog ON so that the movement amount is
longer than the deceleration distance. For details, refer
toPage 405 [Pr.50] Setting for the movement
amount after near-point dog ON.
• Set the smaller value in [Pr.46] OPR speed.
Execute the machine OPR (Positioning start No. 9001).
Execute the machine OPR (Positioning start No.9001)
again.
Install limit switches so that the areas where Near-point
dog signal is on and the hardware stroke limit switch in
the OPR direction is off do not overlap each other.
• Correct the wiring. For details, refer toPage 44
WIRING.
• Correct the program.
• Correct the wiring. For details, refer toPage 44
WIRING.
• Correct the program.
• Correct the control data of the dedicated instruction.
Refer to MELSEC iQ-F FX5 Programming Manual
(Instructions, Standard Functions/Function Blocks) for
more information.
Correct the value of [Cd.17] JOG speed within the setting
range. For details, refer toPage 461 [Cd.17] JOG
speed.
Set a smaller value in [Cd.16] Inching movement amount
to meet the setting condition.
For details, refer to the following.
