♥ The above input and output contact points are shown when setting the torque control mode contact point. (P07-
01,P08-01=25).
(Note) 1 : NF stands for Noise Filter and it must be used to prevent the noise from intruding from
the outside.
(Note) 2 : For the FDA7004/7004B~45 type, connect the single phase AC220V[V] to the r, t terminal,
auxiliary power. FDA7001~02 type does not have the auxiliary power r, t terminal.
(Note) 3 : The recovery resistances of FDA7004~FDA7010 are installed inside the driver as an
internal type. The recovery resistance of the FDA7001, 7002, 7004B, FDA7015 type or
above is the separately installed type. Check the capacity and apply accordingly.
(Note) 4 : Connect the ground wire of CN1 cable to the FG (Frame Ground) terminal.
(Note) 5 : Separate GND24 (CN – 24, 25) and GND (CN1 – 1, 8, 26, 33, 34, 36).
When connect commonness, malfunction of servo drive and burnout can occur.
