data incorrect • The backup data for absolute position restoration is
illegal.
• The home position return has never been executed
after the system start.
• The home position return is started, but not completed
correctly.
• "Absolute position erased" in the driver is detected.

093EH SSCNET
communication error Data received from servo amplifier is in error.
[Operation status at warning occurrence]
The operation continues. • Check the SSCNET

cable.
• Check the servomotor and encoder cable.
• Take measures against noise.
• Check whether the rotation direction selection/travel
direction selection (PA14) is set "0

1" or "1

0"
in the user program or the engineering tool.
0980H Speed change during
deceleration The speed change request is issued during deceleration
stop with JOG start signal OFF.
[Operation status at warning occurrence]
The speed change is not carried out.
Do not carry out the JOG speed change during
deceleration with the JOG start signal OFF.
0981H JOG speed limit
value
The JOG speed
*2
exceeds the JOG speed limit value at
start.
[Operation status at warning occurrence]
• When the speed exceeds the JOG speed limit, the
JOG operation is carried out with the JOG speed limit
value.
• While the speed is limited by the JOG speed limit
value, the "[Md.39] In speed limit flag" is turned ON.
Set a value within the setting range.
0982H JOG speed limit
value
The new speed value
*2
exceeds the JOG speed limit
value when the speed is changed during operation.
[Operation status at warning occurrence]
• When the speed exceeds the JOG speed limit, the
JOG operation is carried out with the JOG speed limit
value.
• While the speed is limited by the JOG speed limit
value, the "[Md.39] In speed limit flag" is turned ON.
Set a value within the setting range.
0988H Outside manual
pulse generator input
magnification range
The manual pulse generator 1 pulse input magnification
is set to 0, 10001 or more, or negative value.
[Operation status at warning occurrence]
• When input magnification is set at 10001 or more, or
negative value: Re-set to 10000.
• When input magnification is set at 0: Re-set to 1.
