Analog
input
excess
protection
39
Higher voltage has been applied to the analog
command input (SPR : CN X5, Pin-14) than the value
that has been set by Pr71 (Analog input excess setup)
This protective function is validated when SPR/TRQR/
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
andPr5B (Torque command selection) is set to 1,
and speed zero clamp is invalidated (Velocity com-
mand is not zero.)
• 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.
Absolute
system
down error
protection
40
Voltage of the built-in capacitor has fallen below the
specified value because the power supply or battery
for the 17-bit absolute encoder has been down.
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.
*Absolute
counter
over error
protection
41
Multi-turn counter of the 17-bit absolute encoder has
exceeded the specified value.
• Set up an appropriate value to Pr0B (Absolute
encoder setup) .
• Limit the travel from the machine origin within 32767
revolutions.
Absolute
over-speed
error
protection
42
The motor speed has exceeded the specified value
when only the supply from the battery has been
supplied to 17-bit encoder during the power failure.
• 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.
*Absolute
single turn
counter
error
protection
44
Single turn counter error of 17-bit absolute encoder
has been detected.
Single turn counter error of 2500[P/r], 5-wire serial
encoder has been detected.
Replace the motor.
*Absolute
multi-turn
counter
error
protection
45
Multi turn counter error of 17-bit absolute encoder has
been detected.
Multi turn counter error of 2500[P/r], 5-wire serial
encoder has been detected.
Replace the motor.
Absolute
status error
protection
47
17-bit absolute encoder has been running at faster
speed than the specified value at power-on.
Arrange so as the motor does not run at power-on.
*Encoder
Z-phase
error
protection
48
Missing pulse of Z-phase of 2500[P/r], 5-wire serial
encoder has been detected
The encoder might be a failure. Replace the motor.
*Encoder
CS signal
error
protection
49
CS signal logic error of 2500[P/r], 5-wire serial encoder
has been detected
The encoder might be a failure. Replace the motor.
