SPL is valid such cases as,
1)Velocity control
when Pr02 (Control mode setup) is set to 1, 3 or 5 and
Pr05 (Velocity setup internal/external switching) is
set to 0 or 2, and when analog velocity command is
selected and speed zero clamp is invalidated. (veloc-
ity command is not zero).
2)Torque control
when Pr02 (Control mode setup) is set to 2 or 4 and
Pr5B (Torque command selection) is set to 0. 3)Tor-
que control
when Pr02 (Control mode setup) is set to 2, 4 or 5
and Pr5B (Torque command selection) is set to 1,
and speed zero clamp is invalidated (Velocity com-
mand is not zero.)

Causes Measures
• Set up Pr71 (Setup of analog input excess) correctly.
Check the connecting condition of the connector, CN
X5.
• Set up a larger value to Pr57 (Filter setup of Velocity
command).
• Set up Pr71 to 0 and invalidate the protective
function.
After connecting the power supply for the battery, clear
the absolute encoder. (Refer to P.271, "Setup
(Initialization) of Absolute Encoder" of Supplement.)
You cannot clear the alarm unless you clear the
absolute encoder.
• Set up an appropriate value to Pr0B (Absolute
encoder setup) .
• Limit the travel from the machine origin within 32767
revolutions.
• Check the supply voltage at the encoder side
(5V±5%)
• Check the connecting condition of the connector, CN
X6.
• You cannot clear the alarm unless you clear the
absolute encoder.
Replace the motor.
Replace the motor.
Arrange so as the motor does not run at power-on.
The encoder might be a failure. Replace the motor.
