ADJUSTMENT OF SERVO
6-2
6-1) Basic adjustment
The servomotor must be tuned so that it reliably obeys commands sent from the host controller.
The tuning method of FALDIC-
β
Series includes three types: auto tuning, semi-auto tuning and manual
tuning (parameter #5).
Be sure to operate the servomotor in the auto tuning mode (factory setting) for the first time when
operating it.
The factory setting of FALDIC-
β
Series is auto tuning.
Select semi-auto tuning and adjust
parameter #6 (inertia ratio) and
parameter #7 (gain adjustment).

Decrease the acceleration/
deceleration rate of command
pulse (or, extend the acceleration/
deceleration time).
The torque limit functions.
*2
*1. Assume the inertia ratio in monitor mode 09 (load
inertia ratio) at the keypad panel.
If the inertia ratio is not assumed correctly
1.
Fluctuation becomes large and the maximum
value exceeds two times the minimum value.
2.
The assumed value does not change from “5.0”
(initial value).
The inertia ratio may not be assumed correctly in the
following cases.
1.
Load fluctuation is large.
2.
Friction force is large.
3.
Application with thrust force
4.
Slow acceleration and deceleration
*2. Check monitor mode 03 (peak torque) at the keypad
panel.
If the monitored value is the same as the maximum
current limit (parameter #23), the torque limit is
functioning (initial value: 300%).
