Higen FDA7000 Series - Gain Adjustment of Torque Servo

5. Servo operating
4-17
FDA7001 ~ 02 type does not have control circuit power r, t terminals.
(Note3) The regenerative resistor of FDA7004 ~ FDA7010 is built-in and is mounted inside
the drive. The regenerative resistance of FDA7001, 7002, 7004B and FDA7015 ~
7750 models is a separate type. Please apply after confirming the capacity.
Please contact our sales team for regenerative resistance of models FDA7075 ~
7750.
(Note4) Be sure to ground the ground wire of CN1 cable to FG (Frame Ground) terminal.
(Note5) Apply the Z phase pulse when outputting by line drive method.
(Note6) Apply the Z phase pulse when outputting by open collector method.
(Note7) Be sure to connect GND24 (CN1-24, 25) and GND (CN1-1, 8, 26, 33, 34, 36)
separately.
In case of common connection, malfunction or damage of servo drive may occur.

Torque control
If you suspect that machine vibration is being caused by the servo system, try to adjust the
Analog TRQ TC. It can reduce the vibration. The lower the value, the better control response will
be, but if set too high, it may reduce the responsiveness.
