14 TROUBLESHOOTING
14.5 List of Error Codes
1944H Count method
movement
amount fault 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 OPR speed to the deceleration stop.
[Operation of when the error has occurred]
The machine OPR is not started. • 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
415 [Pr.50] Setting for the movement amount after near-
point dog ON.
• Set the smaller value in [Pr.46] OPR speed.
1945H OPR request
ON 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. Execute the machine OPR (Positioning start No.9001).
1946H OPR restart not
possible 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. Execute the machine OPR (Positioning start No.9001) again.
1947H Signal allocation
error 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 3 sudden stop selection of detailed parameter 2
(deceleration stop/sudden stop). 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.
1949H ABS
transmission
time out 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. • Correct the wiring. For details, refer to  MELSEC iQ-R
Positioning Module User's Manual (Startup).
• Correct the program.
194AH ABS
transmission
SUM • Correct the wiring. For details, refer to

MELSEC iQ-R
Positioning Module User's Manual (Startup).
• Correct the program.
• Correct the control data of the dedicated instruction. For
details, refer to

(Instructions, Standard Functions/Function Blocks)
1980H Outside JOG
speed range 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. Correct the value of [Cd.17] JOG speed within the setting
range. For details, refer to

Page 474 [Cd.17] JOG speed.
1981H Inching
movement
amount error The value to meet the setting condition is not set in [Cd.16]
Inching movement amount. (The setting value is large.)
Setting condition: (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.
Set a smaller value in [Cd.16] Inching movement amount to
meet the setting condition.
For details, refer to the following.

1990H Error before
simultaneous
start • The partner axis for the simultaneous start is in BUSY state.
• The partner axis for the simultaneous start does not exist.
[Operation of when the error has occurred]
The operation is not performed.
• Start the operation after BUSY state of the simultaneous
starting axis is cleared.
• Specify an axis that exists for the simultaneous starting
axis.
1991H • The simultaneous starting axis start data No. of the starting
axis is 0 or a value outside the setting range.
• The simultaneous starting axis start data No. of the axis
other than the starting axis is a value outside the setting
range.
[Operation of when the error has occurred]
The operation is not performed.
Correct the simultaneous starting axis start data No. For
details, refer to the following.
