* SPEED I-GAIN INHIBITION
The speed I-gain function is disabled when this value is set in "1".
In the result, the structure of speed controller is changed from PI to P
control regardless of speed I-gain value.
If the servo motor at a stop is rotated even one pulse due to an
external factor, it generates torque to compensate for a position
mismatch. When the shaft is mechanically locked at a stop after
positioning end, the setting value "1" suppress the unnecessary torque
which attempts to compensate for position mismatch.
If the speed I-gain function is valid under the mechanically locked
condition, the servo motor and amplifier may be damaged by the over
load.

06 DEVER
* OVER DEVIATION PULSE
Used to set the allowable maximum pulses of deviation (error) counter.
The unit is 10 pulse.
The deviation counter is the error pulse counter (command-feedback
pulse). If the value of deviation counter is higher than the setting value
in this parameter then the motion stops and error message
(
"DEVIATION ALARM
") is displayed.
When this alarm has occurred, eliminate its cause, ensure safety, and
deactivate the alarm before restarting operation.
The causes of over deviation alarm are mainly as follows.
1. Acceleration/deceleration time is too small.
2. Position control p-gain value is too small.
3. Torque limit value is too small
4. Machine lock

07 TRQLT
* MAXIMUM TORQUE LIMIT
Set to define the maximum torque. The unit is % of the rated torque.
The factory setting value (300% of rated torque) is applicable for the
most operation.
In case of the heavy inertia or the easy fragile machine, the setting
value may be reduced at the recommended torque value. But, the too
small setting value makes the slow response time, over load or over
deviation alarm.

08 MAXSP
* MAXIMUM SPEED LIMIT
Used to set the allowable maximum speed. The unit is rpm.
The maximum speed of each servo motor models are different from
each other. The factory setting value is the maximum speed of it's own
model and applicable for the most operation.
For a 1 second, if the running speed is higher than the setting value
then the motion stops and error message (
"OVER SPEED ALARM"
) is
displayed. When this alarm has occurred, check the program and
parameters carefully and restart.
Notice that the servo motor may be damaged permanently due to the
setting value more than factory setting value.
