Troubleshooting Tables
Section 11-1
53
There is slippage in
positioning.
The slippage is not constant.
Malfunction due to noise.
Is shielded cable being used?
Use shielded cable.
54
There was already slippage in
the position of the origin
before positioning was per-
formed.
Refer to 25 and 26.
Refer to 25 and 26.
55
The shield is not properly
grounded at the Servo Drive.
Check the ground wiring.
Correct the wiring.
56
The PCU’s output power sup-
ply is not separated from
other power supplies.
Check whether the PCU’s output
power supply is separated from
other power supplies.
Separate the PCU’s out-
put power supply from
other power supplies.
57
Install a noise filter at the
primary side of the PCU’s
output power supply.
58
Ground the PCU’s output
power supply.
59
The cable between the PCU
and the Servo Drive is too
long.
-–-
The maximum cable
length is two meters for
open collector output
models and five meters
for line driver output mod-
els.
60
Twisted-pair cable is not being
used for the pulse outputs.
Check whether twisted-pair
cable is being used for the pulse
outputs.
Use twisted-pair cable for
pulse outputs.
61
The cable between the PCU
and the Servo Drive is not
separated from other power
lines.
Check whether the cable is sep-
arated from other power lines.
Separate the cable from
other power lines.
62
There is malfunctioning due to
noise from a welding
machine, inverter, etc.
Check whether there is a device
such as a welding machine or
inverter nearby.
Separate the Unit from
the noise source.
63
Output for operating com-
mands turns OFF during oper-
ation.
Check whether the Servo Drive’s
operating command output sig-
nals are turning OFF during
operation.
Turn ON the operating
command output signals
with the correct timing.
64
There is slippage in the
mechanical system.
Check for slippage by marking
the mechanical connections.
Tighten the connections.
65
Speeds drops (or
operation stops)
during continuous
operation
The minimum operating time
(10 ms min.) is not achieved.
Calculate the movement time by
dividing the amount of move-
ment by the speed to check
whether operation is longer than
the minimum operating time.
Add the minimum operat-
ing time and other fac-
tors, and adjust the target
distance and speed so
that the movement time
will be greater than this
total.
66
When memory
operation is tempo-
rarily stopped and
then restarted, it
starts from the
beginning again
(not from where
operation was tem-
porarily stopped)
When operation is restarted,
the Sequence Number Enable
Bit is ON at the point when the
START Bit is turned ON.
Check the ladder program and
data trace.
Change the ladder pro-
gram so that the
Sequence Number
Enable Bit is turned OFF
when the START Bit is
turned on to resume
operation.
No.
