Encoder
communication
data error
protection
Data communication between the
encoder is normal, but contents of data
are not correct.
Mainly data error due to noise. Encoder
cables are connected, but communication
data has some errors. • Secure the power supply for the encoder
of DC4.90 V to 5.25 V)...pay an attention
especially when the encoder cables are
long.
• Separate the encoder cable and the motor
cable if they are bound together.
• Connect the shield to FG.
24 0 Position
deviation
excess
protection
Deviation pulses have exceeded the
setup of Pr0.14.
1) The motor movement has not followed
the command.
2) Setup value of Pr0.14 (Position
deviation excess setup) is small.
1) Check that the motor follows to the position
command pulses. Check that the output
toque has not saturated in torque monitor.
Make a gain adjustment. Set up maximum
value to Pr0.13 “1st torqur limit” and
Pr5.22 “2nd torqur limit” . Make a encoder
wiring as per the wiring diagram. Set up
the longer acceleration/deceleration time.
Lower the load and speed.
2) Set up a larger value to Pr0.14.
1 Speed
deviation
excess
protection The difference between the internal
positional command speed and actual
speed (speed deviation) exceeds the
setup vale of Pr6.02.
Note) If the internal positional command
speed is forcibly set to 0 due to
instantaneous stop caused by the
command pulse inhibit input (INH) or
CW/CCW over-travel inhibit input, the
speed deviation rapidly increases at this
moment. Pr6.02 setup value should have
sufficient margin because the speed
deviation also largely increases on the
rising edge of the internal positional
command speed.
• Increase the setup value of Pr6.02.
• Lengthen the acceleration/deceleration
time of internal positional command speed,
or improve the follow-up characteristic by
adjusting the gain.
• Disable the excess speed deviation
detection (Pr6.02 = 0).
26 0 Over-speed
protection
The motor rotational speed has exceeded
the setup value of Pr5.13. • Do not give an excessive speed command.
• Check the command pulse input frequency
and division/multiplication ratio.
• Make a gain adjustment when an overshoot
has occurred due to a poor gain adjustment.
• Make a wiring connection of the encoder as
per the wiring diagram.
1 2nd Over-
speed
protection The motor rotational speed has exceeded
the setup value of Pr6.15.
Note
• When protective function marked with * in the protective function table is activated, it cannot
be disabled by the alarm clear input (USB conmmunication(PANATERM) or RTEX alarm
clear commond). To return to the normal operation, turn off power, and then turn on power
again,or use soft reset commond by RTEX conmmunication.
