The power supply should be connected only to the R, S, or T terminal. Connecting to a different terminal may cause fire.

Caution

Wrong wiring of motor armature wires U, V, and W may drive the motor out of control.

Check connections before starting operation.

Caution

Note 1 : Separate the power supply and motor armature wiring from the motor sensor cable.

Note 2 : Connect the motor earth to the servo amplifier earth terminal and ground the servo amplifier without fail.

Note 3 : Install a surge killer to the contactor and relay coils to prevent the influence of noises.

Note 4 : A DCL terminal may be added to P1 and P2 terminals for the purpose of improving the power factor and suppressing the harmonic component. (Motor capacity : below 4kw)

Note 5 : CN6, 7, and 8 are connector numbers for 035P and 070P. Codes for 100P are in brackets ( ), and those for 200P are indicated in another table.

Note 6 : Connect the grounding for 200P to the terminal block of TB1.

(2) When the holding brake (MB) is applied:

Note 1 : Make sure that the sequence I/O includes "MB confirmation" and "MB output." An alarm (AL-14: brake abnormal) will be issued when MB and DB operation is not confirmed. Particular care is required when the user parameter UP-46 (sequence I/O option) is set to "special sequence."

Note 2 : When you stop operation the speed starts reducing, and when the revolution rate falls to the brake-ON level, the holding brake is applied. The brake application settings are specified with the user parameter UP-13. When UP-13 is equivalent to zero (0), the deceleration time becomes zero, and the holding brake start working when the actual revolution slows down below the brake ON revolution rate (UP-14).

Note 3 : A revolution rate at which the holding brake is applied may be set with the user parameter UP-14 (brake ON revolution rate). The parameter is for avoiding applying the holding brake instead of the speed control brake, and prevents the holding brake from application until the revolution rate falls below a set level.

Note 4 : When PON is turned OFF or an alarm is issued, the servo is unlocked and the brake is applied. Do not turn PON off frequently during operation.
